Part II Plenary Speeches

Plenary Speech 1: Internet+Robot Will Drive Next Generation Mobile

Communication Standard

Speaker: Prof. Xiaoqing Huang, China Mobile Research Institute, China Time: 08:50-09:30, Tuesday Morning, September 22, 2015

Location: Yuehai Hall(粤海厅), 3rd Floor, Guangdong Hotel (Shanghai) Abstract My talk will introduce the concept and architecture of cloud connected mobile robots. It is pointed out that for 5G, the key demand for is no longer for human communication，but for smart machines.

Plenary Speech 2: Big Data Analytics for Wireless Networks

Speakers: Prof. Robert Caiming Qiu, Tennessee Technological University (TTU), USA Prof. Prof. Shengjie Zhao, Tongji University, China Time: 09:30-10:10, Tuesday Morning, September 22, 2015

Location: Yuehai Hall(粤海厅), 3rd Floor, Guangdong Hotel (Shanghai)

Plenary Speech 3: Version 2020 form CMCC

Speaker: Dr. Chih-Lin I, China Mobile Research Institute GCRC, China Time: 10:30-11:10, Tuesday Morning, September 22, 2015 Location: Yuehai Hall(粤海厅), 3rd Floor, Guangdong Hotel (Shanghai) Abstract The 5G wireless communication network, which may come into life in around


2020, is expected to accommodate the extremely diverse performance requirements of the rich applications in Mobile Internet and Internet of Thing. For lack of enough flexibility to satisfy the diverse needs due to its dedicated hardware based deployment schemes and single globally optimized air-interface protocol, the traditional mobile network is well motivated to become soft in 5G era. A “Soft 5G” concept is proposed by China Mobile, with reconfigurable and software defined network and air interface. This brings agility into implementation of each network element from core network to access network, as well as the building blocks of the air interface. This talk will share the latest development within China Mobile on the key elements of “Soft 5G” concept, i.e., SDN/NFV, C-RAN, and SDAI.

Plenary Speech 4: Some Advances inWireless Networkingfor Cyber Physical

Systems

Speaker: Prof. Tom Hou, Virginia Polytechnic Institute and State University, USA Time: 14:00-14:40, Tuesday Afternoon, September 22, 2015

Location: Yuehai Hall(粤海厅), 3rd Floor, Guangdong Hotel (Shanghai) Abstract Our world is evolving into a smart planet. The driving force in this evolution is the marriage of cyber and physical systems (or CPS). CPS is a synergy of technologies such as control, sensing, communications, networking, computation, among others. In this talk, I will focus on some new advances in wireless networking that are important to CPS. First, we consider throughput in multi-hop wireless networks – a fundamental problem in CPS. Given that MIMO is now pervasive, we study how to exploit MIMO’s capability in a multi-hop network environment. The key challenge here is to efficient use of MIMO’s degree-of-freedoms (DoFs) to cancel interference from other nodes in the network. Second, we consider energy problem in sensor networks – another fundamental problem in CPS. We present our research on wireless energy transfer, a new enabling technology to address energy problem in battery-powered wireless networks. Finally, I will describe some new frontiers in sharing radio spectrum and coexistence between primary and secondary networks beyond dynamic spectrum access. Most of these research advances areinterdisciplinary and require a synergistic exploration of knowledge basesfrom multiple technical domains.


Plenary Speech 5: The Introduction of Overlapped Multiplexing Principle and Its

Applications

Speaker: Prof. Daoben Li, Beijing University of Posts and Telecommunications, China Time: 14:40-15:20, Tuesday Afternoon, September 22, 2015

Location: Yuehai Hall(粤海厅), 3rd Floor, Guangdong Hotel (Shanghai) Abstract The Overlapped Multiplexing Principle is a newly revealed principle in communication thathas been listed as one of the key projects of the coming 5 years plan by NNSFof China (National Nature Science Foundation). The principle points out that the overlapping between adjacent and neighboring data in any communication system is never interference but a beneficial coding constraint relationoffering benefit coding gain. The destroy fact coming outside the system is only the interference. According to it, all nowadays system seems unreasonable due to that they wasted most of their energy to combat with the beneficial“interference”. Based on such principle, a novel OVXDM (Overlapped X Domain Multiplexing)coding schemein X domainisappeared. By the shifted data weighted overlappedversion of any band-limited multiplexing transfer function, any time duration limited multiplexing impulse response functionor any other domain multiplexing function with limited duration, there appears an OVXDM with high spectral efficiency, high coding gain, no coding redundancy, relative low decoding complexity. Both theoretical analysis and testified simulations show that OVXDM is suitable for high spectral efficiency application and its capacity is only roughly linear to SNR rather than the well-known logarithm to SNR.

Plenary Speech 6: Beyond Cyber-Physical Era: What's Next?

Speaker: Prof. Sajal K. Das, Missouri University of Science and Technology, USA Time: 15:20-16:00, Tuesday Afternoon, September 22, 2015

Location: Yuehai Hall(粤海厅), 3rd Floor, Guangdong Hotel (Shanghai) Abstract We live in an era of “Internet of Things” where our physicaland personal environments are becoming increasingly smarter as they are immersed with sensing, networking, computing and communication capabilities. The availability of rich mobile devices like smartphones and wireless sensors have also empowered humans as an integral part of


cyber-physical systems. This synergy has led to cyber-physical-social convergence exhibiting complex interactions, interdependencies and adaptations among devices, machines, systems/environments, users, human behavior, and social dynamics. In such a connected and mobile world, almost everything canacts as information source, analyzer and decision maker. This talk will highlight some of the emerging research challenges and opportunities in cyber-physical-social convergence, and then present some novel solutions to tackle them. It will also reflect on a fundamental question: “What’s Next?”

Plenary Speech 7: Time Reversal Indoor Localization System Employing Spread

Spectrum Acoustics

Speaker: Prof. Kosai Raoof, University of Maine, France Time: 16:20-17:00, Tuesday Afternoon, September 22, 2015

Location: Yuehai Hall(粤海厅), 3rd Floor, Guangdong Hotel (Shanghai) Abstract In this keynote, we present an acoustic indoor localization system that allows a simultaneous localization of sources with different location precision. We propose a new method employing time reversal technique and the code-division multiple-access modulation CDMA. The system was evaluated in simulations and experiments while varying the number of sources and that of the precision levels. The effect of the signal-to-noise ratio on system performance is also studied. With this system, we aimed to reduce the audibility of the transmitted acoustical signals. An equalization filter based on the absolute threshold of hearing was applied to the emitted signals and a matched filter was proposed at the receiver. Results showed an improvement in location precision when compared to the location system without the equalization filter. A reduction in signal audibility was also achieved.

This method uses the characteristics of information scattered encoding and non-rate transmission of LT codes, through the spectrum of the signals which is the direct sequence spread spectrum broadening coding, which makes it have a good link with anti-flash and anti-jamming capability.

Article ID: 70008 Title: Alpha Stable Distribution P Order Spectrum with its Frequency Domain Characteristics Analysis Name: JIANG Jinlong Affiliation: Jiujiang University E-mail: [email protected] Abstract Alpha stable distribution has not the usual power spectral density. The current fractional lower order spectrum definitions, such as alpha spectrum, covariation spectrum, fractional lower order covariance spectrum and geometric power spectrum, etc., all use the fractional lower order transform so that there are two order statistics for transformed signals. But the fractional lower order

transform will cause the changes of frequency spectrum. For this purpose, the first order spectrum of alpha stable distribution is defined in this paper, it is simple in calculation and does not change the frequency domain characteristics, and can be extended to p order spectrum. The frequency domain characteristics of fractional lower order transform are analyzed, introduced the frequency domain of the highest order of convergence of the p order spectrum and related characteristics. Simulation results show that the correctness of the theory. Article ID: 70009 Title: Performance Analysis of Intrusion Prevention System on Cyber Security for Voice over Internet Protocol (VoIP) Name: Auttapon pomsathit Affiliation: Computer engineering Rajamangala University of Technology Rattanakosin Phutthamonthon, Nakhon Pathom E-mail: [email protected] Abstract This research evaluated the cyber security effectiveness of the intrusion prevention system for Voice over Internet Protocol (VoIP) focusing on the defense of Denial of Service (DoS) which propose to disturb server providing VoIP services.

Article ID: 70010 Title: Hybrid Orthogonal Frequency Division Multiplexing (H-OFDM) for Visible Light Communication Name: Zhang Jun Affiliation: Information Science and Technology Institute E-mail: [email protected] Abstract In this paper, we present a novel hybrid orthogonal fre-quency division multiplexing (H-OFDM) for visible light communication (VLC). H-OFDM uses a combination of DC-bias optical OFDM (DCO-OFDM) and asymmetrically clipped optical OFDM (ACO-OFDM) techniques. In this hybrid technique, the absolute value of bipolar DCO-OFDM signal is used to carry amplitude information in the first block, while the ACO-OFDM signal is used to transmit the polarity information of the DCO-OFDM signal in the second block. This new technique does not need any DC bias and could achieve maximum 33.3% increase of data rate with 256-QAM in theory. Extensive simulations notice that H-OFDM results in almost 3dB performance improvement with an additive white Gaussian noise. In addition, it saves up to 2dB input electrical average power when negative clipper and power allocation are applied. Therefore, with no DC bias, data rate increment and power efficient, H-OFDM seems to be an attractive technique for VLC system using intensity modulated di-rect detection (IM/DD). Article ID: 70011 Title: On the Capacity for 3D LoS MIMO Channels in Short-Range Millimeter Wave Communications Name: Xumin Pu Affiliation: National Key Laboratory of Science and Technology E-mail: [email protected] Abstract This paper investigates the capacity of NX2 short-range

line-of-sight (LoS) multiple-input multiple-output (MIMO) channels at millimeter wave (mm-wave) frequencies in three-dimensional (3D) space. First, the channel with arbitrary antenna orientations in 3D space is modeled using the spherical-wave model (SWM). Then, the analytical expression for the corresponding capacity without channel state information (CSI) at the transmitter is obtained. Both the analytical and simulation results show that the capacity of short-range mm-wave LoS MIMO channels is completely determined by the wavelength, the number of transmit (Tx) antennas, the inter-element spacings, the transceiver distance and the orientations of the arrays. It is shown that the capacity fluctuates significantly with these parameters. Furthermore, for the shorter wavelength, the smaller inter-element spacings can be obtained for the maximum capacity with the SWM. Meanwhile, the shorter wavelength is more appropriate in short-range communications. Article ID: 70014 Title: Efficient Clustering Routing Algorithm Based on Opportunistic Routing Name: Kunpeng Wang Affiliation: Dalian University of Technology E-mail: [email protected] Abstract Based on the analysis of the existing classic clustering routing algorithm HEED, this paper proposes an efficient dynamic clustering routing algorithm ED-HEED. In the cluster selection process, in order to optimize the network topology and select more proper nodes as the cluster head, the proposed clustering algorithm considers the shortest path prediction of the node to the destination sink and the congestion situation. In the data transmission procedure, the high-efficiency CEDOR opportunistic routing algorithm is applied into the ED-HEED as the data transmission mode between cluster headers. A novel adaptive dynamic clustering mechanism is also considered into the algorithm, as well as the data redundancy and security control. Our Simulation demonstrates that the ED-HEED algorithm can reduce the energy consumption, prolong the network life and keep the security and


availability of the network compared with the HEED algorithm.

Finally, we implement and test the effectiveness of the improved scheme. Article ID: 70025 Title: A Parameter Estimation Scheme for Multi-component BPSK Interferences Name: Li Jian Affiliation: national univsersity of defence technology E-mail: [email protected] Abstract BPSK interference is also called the matched spectrum interference, because its wave form and frequency coverage matches that of satellite navigation signal. As efficient wideband interference, it heavily menaces the safety of Global Navigation Satellite System (GNSS) and is taken as an important target of interference monitoring. However, there are hardly any researches on signal separation and parameter estimation of non-cooperative muti-component BPSK interferences. Thus, a parameter estimation scheme for multi-component BPSK interferences based on a modified Phase Lock Loop (PLL) is put forward. Simulations show that the proposed scheme


has equal code Bit-Error-Ratio to that of cooperative Successive Interference Cancellation (SIC).

Article ID: 70037 Title: Subcarrier Allocation Algorithm based on User Demand for SC-FDMA System Name: Fang Ye Affiliation: Harbin Engineering University E-mail: [email protected] Abstract This paper investigates the Dynamic Subcarrier Allocation (DSA) issue in Long Term Evaluation (LTE) uplink. Many researches pay more attention on maximizing the system throughput or improving the fairness between multi-users, however, they ignored the user actual spectrum demand. In this paper, an improved subcarrier allocation scheme has been proposed, which considers the

user demand of quality of services (QoS) especially the demand of transmission capacity. In this paper we study on how to satisfy the users’ capacity demand with also to guarantee throughput to some extent. The scheduler allocates a chunk to the user with largest capacity demand in greedy way and renews all the users’ requests before the next allocation, so that the algorithm can meet users’ demand as far as possible. By making a comparison with other existent allocation algorithms, we can see that the proposed algorithm achieves better demand satisfaction without computational complexity increase through exhaustive simulations.

Article ID: 70048 Title: Resource Allocation in Ofdm-Based Cooperative Cognitive Radio Networks with Two-Way Amplify-and-Forward Relay Name: Lijie Wang Affiliation: Xi’an Satellite Control Center E-mail: [email protected] Abstract In this paper, we investigate the subcarrier allocation and

power adjustment to maximize the sum data rate of the secondary users with limited interference to the primary users in OFDM-based cooperative cognitive networks. A fixed common relay is introduced to forward the data of the secondary users by adopting two-way amplify-and-forward (AF) relay. By categorizing the subcarriers into 2 classes, the idle subcarriers and the busy subcarriers, we analyze the resource allocation problem for them and propose a resource allocation scheme which limits the power interferences caused to primary user and maximizes the sum date rate of the secondary users. The simulation results show that the proposed scheme can significantly increase the sum data rate Article ID: 70049 Title: Pilot Contamination Reduction Based on Improved Pilot Power Control in M-MIMO Systems Name: Shuo Ma Affiliation: Chengdu University of Information Technology E-mail: [email protected] Abstract In multi-user Massive MIMO (M-MIMO) TDD systems, the performance of achievable rates in UL/DL is limited by pilot contamination with the number of BS antennas grows. On the basis of a simplified channel model which allows us to obtain the achievable rates easily, the inter-cell interference factor is defined as “orthogonality factor” for the first time in this paper. The orthogonality factor is denoted by the orthogonality of pilots from interference cells to the target cell. We propose an improved pilot power control scheme. We consider the partial pilot power control scheme with dividing the time slot of pilots into two parts and making the pilots staggered only from interference cells, while pilots from the target cell are still transmitted in the whole time slots. As a consequence, the inter-cell interference factor is always reduced to half with the proposed scheme. In addition, we also obtain an additional conclusion that the inter-cell interference factor decreases with the increase of the number of UTs. Ultimately, the pilot contamination is mitigated and the achievable sum rates are improved significantly with the proposed scheme. The numerical results demonstrate the


proposed scheme is effective obviously. Article ID: 70050 Title: Energy-efficient Dynamic Traffic Offloading in HetNets Name: Xun Wang Affiliation: UESTC E-mail: [email protected] Abstract With the anticipated exponentially increasing traffic demand in future mobile networks, energy consumption becomes a significant challenge of the information and communication technology industry. Heterogeneous network (HetNet) is a promising infrastructure for both expenditure and energy saving for cellular operators and has attracted intensive research interest. In HetNets, offloading traffic from macro base station (BS) to Low Power Nodes (LPNs) is expected to be a promising method in improving energy efficiency of cellular networks. In this paper, we propose a dynamic traffic offloading scheme to improve energy efficiency of HetNets. We model the traffic offloading in HetNets as a dynamic programming (DP) problem, where the delay tolerance of data traffic is taken into account. We conduct simulation experiments based on the model with realistic broadband channel propagation conditions to verify the effectiveness of our proposed traffic offloading scheme. Numerical results show that compared with Reference Signal Received Power (RSRP) based offloading algorithm, our proposed algorithm can effectively improve energy efficiency (EE). Article ID: 70052 Title: A Digital differentiator-based MSK demodulator in a zero-IF receiver for 2.4 GHz Zigbee applications Name: Meilin Wan Affiliation: Huazhong University of Science and Technology E-mail: [email protected] Abstract

A new digital differentiator-based demodulator in a zero-IF receiver for 2.4 GHz Zigbee applications is proposed. It receives the In-phase (I) and Quadrature-phase (Q) signals which are oversampled and quantized by a 4-bit ADC @ 8MHz. Two one-order digital differentiators based on Taylor series, two multipliers and an adder are adopted to calculate the derivative of the signal phase. Then an Inte-grate-and-Dump Filter (IDF) is applied to obtain the phase difference in the chip time and determine its sign as the transmitted data. No complex carrier synchronization is needed and the demodulator can achieve low power con-sumption and low cost for its simple architecture. The theoretical analysis of Chip Error Rate (CER) under Addi-tive White Gaussian Noise (AWGN) environment is also presented. The simulation results show that the proposed demodulator achieves Packet Error Rate (PER) of 1% with Carrier Frequency Offset (CFO) of 200 KHz and Signal-Noise Ratio (SNR) of 9.4 dB. Article ID: 70054 Title: A Self-similar Call Admission Control Algorithm in WiMAX Name: Yongdong Hu Affiliation: Southeast University E-mail: [email protected] Abstract Modelling WiMAX network traffic based on the self-similarity character is better than the traditional model based on the Poisson process, because the former can provide more accurate calculation for effective bandwidth. In this paper we propose a WiMAX network traffic model based on M/Pareto model to describe its self-similarity character. Then we deduce the average transmission rate and the variance coefficient for the FBM traffic model by the M/Pareto model, and get the Hurst parameter of the FBM traffic model by statistical analysis method. By the FBM traffic model we get a formula for calculating the effective bandwidth. Accordingly, we propose a modified self-similar call admission control algorithm (SS-CAC). SS-CAC can avoid measuring the parameter values of FBM traffic flow to do call admission control. Simulation results show that SS-CAC greatly reduces the call


blocking rate and improves the bandwidth utilization.

Article ID: 70056 Title: Extended Wireless Mesh Network For Vanet With Geographical Routing Protocol Name: Jinwoo Nam Affiliation: Korea University E-mail: [email protected] Abstract A vehicular ad-hoc network (VANET) is a promising technology in near future. VANET allows vehicles to communicate with each other and with roadside units (RSUs). Wireless Access in Vehicular Environment (WAVE), defined by IEEE, provides the Internet con-nectivity for vehicles as well as vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communica-tion. RSUs can form a wireless mesh network (WMN) as a backbone infrastructure to enhance the perfor-mance of VANET. However, WAVE supports only one-hop communications for IP packets in VANET, and existing researches do not consider the compatibility between VANET and WMN infrastructure formed by RSUs. We propose the extended WMN (ExWMN) which has the feasibility to extend WMN to VANET domain. In

ExWMN, the vehicles can send IP packets to an access router by using the multi-hop capability of WMN. ExWMN uses the addressing scheme of WMN for the extended VANET domain and exploits geo-graphical routing protocols instead of existing routing protocols of WMN due to VANET characteristics such as mobility and dynamically changing network topolo-gies. ExWMN supports the compatibility between the extended VANET and a WMN infrastructure due to RSUs, which provide a bridging function between them. This paper presents the architecture and the detailed procedures of the ExWMN.

The maximum SINR criteria is used for selecting optimal codeword from the Grassmannian codebook and perturbation codeword at the receiving, and feedback the Grassmannian precoding codeword index and perturbation codeword index to the transmitter, then the array preprocessing is used at the transmitter and receiver to get optimal capacity, and compensating for the performance loss due to the limited feedback. Simulation results show that the proposed method to ensure the cost of the feedback link, the system throughput and BER performance are improved effectively.

Abstract As networks are continuously growing, their operation and management are becoming more and more complex. In consequence, current network monitoring systems generate a huge volume of measurement data which represents one of the most critical issues in the management of computer networks. This paper is dedicated to the challenges in network traffic monitoring. It provides a brief overview of several issues that arise during traffic measurements. We inspect the issues form three viewpoints: (i) the impact on the inter-networking devices, (ii) resource asymmetry and (iii) real-time data evaluation. To quantify the volume of measurement data and its cost we also performed two experiments. They were focused (i) on the estimation of the average volume of data that must be processed during monitoring along with its impact on system resources and (ii) on the cost of interpretation of the measurement data. The paper is concluded by some re-marks on the directions at which should the research and development be aimed as well as with a brief introduction of our idea for addressing the described issues. Article ID: 70059 Title: Adaptive Multi-user Uplink Resource Allocation with Imperfect CSI Name: Yuanyuan Zhang Affiliation: Institute of Electronics, Chinese Academy of Sciences E-mail: [email protected] Abstract In this paper, the effect of the imperfect channel state information (CSI) on the system performance of the radio resource management is investigated for the uplink trans-mission in multi-user CDMA systems. The imperfect CSI introduces the constellation-point dependent symbol error rate (SER), which correspondingly yields the nonconvex and nondifferentiable throughput function. Then, a bisec-tion based iteration algorithm is proposed to solve the throughput maximization problem subject to certain pow-er constraints.

Article ID: 70071 Title: Software Attribute Trades-off and Conflicts in a Network Management System Name: Shahnawaz Qureshi Affiliation: Blekinge institute of technology E-mail: [email protected] Abstract Software platform is an emerging field and progressively more popular in software engineering. Software platform has become an essential part in development of software. Prototyping is possibly one of the most commonly used learning paradigms in software platform. Hence, it is reasonable to accept some of the requirements that could be expressed as specific quality attributes for developing and comparative analysis of prototype. Modern software applications must provide high availability, less development cost and performance. They must also be


maintainable in order to reduce the maintenance cost. In this paper, we investigate the significance of quality attributes for different software platforms. Three prototypes were built by deploying different software platforms such as PHP, JSP and Perl. Each of these prototypes were evaluated with respect to maintainability, performance and implementation cost. We have shown the possibility to achieve better quality attributes given to a certain network management system. We also shown that there is trade-off, the best implementation alternative depends on how important the different quality attributes are in a certain situation. Article ID: 70073 Title: An Interference Alignment based on Joint Projector Interference Distances Name: Junchao Yao Affiliation: Harbin Engineering University E-mail: [email protected] Abstract Interference alignment (IA) effectively improves the ca-pacity of interference channel by overlapping the interfer-ence and eliminating at the receivers. At present, most algorithms of the distributed interference alignments de-sign precoder and receiver filter at both transmitters and receivers which causes overhead. This paper presents an improved interference alignment based on minimizing projector interference distances, introduces joint distance and optimizes the subspace projector distances between interference and desired signals to achieve interference alignment by steepest descent algorithm based on complex Grassmann manifold. The proposed algorithm alleviates the overhead for designing precoding matrixes at one side. Simulation results suggest that the proposed approach obtains higher sum rate compared with the previous algorithms and faster rate of convergence compared with the old approach only based on the projector interference distances.

Title: A Joint Resources Allocation Approach for Hybrid Visible Light Communication and Lte System Name: Lu Li Affiliation: Beijing University of Posts and Telecommunications E-mail: [email protected] Abstract Visible light communication (VLC) is regarded as an emerging wireless access technology that has tremendous potential for 5G. However, the link of VLC is vulnerable to blockage of moving objects within the room. Moreover, the link data rate of VLC falls sharply with link distance increasing. Therefore, VLC needs to constitute networks with other wireless technologies, such as WiFi, WiMAX, 2G/3G and LTE, etc. Considering an indoor scenario, this paper proposes a heterogeneous network model of a hybrid VLC and LTE system. On this basis, a joint resources management strategy water-filling-iteration-ex- tremum (WFIE) is developed by thinking over characteristics of VLC physical layer. WFIE firstly selects the best network by detecting channel condition in heterogeneous network. Then WFIE uses water-filling algorithms to allocate power and takes extremal method to allocate frequency. Simulation proves that our scheme improves the throughput of system compared with conventional method, besides taking into account the quality of service and fairness. Article ID: 70079 Title: Priority-Based Bandwidth Allocation in Heterogeneous Wireless Network Name: Liu Yuhan Affiliation: University of Electronic Science and Technology of China E-mail: [email protected] Abstract In this paper, a priority-based bandwidth allocation in the context of heterogeneous wireless network is studied. By utilizing the mobile terminals with multi-homing capability, that simultaneously accessing bandwidth from different wireless network, a novel utility-based bandwidth allocation approach is introduced. An essential

factor is the priority mechanism considering the services priority classification, which means the higher-priority service request can be guaranteed on bandwidth allocation prior to the lower-priority service request. The utility function is used to distinguish both the service priority and the network subscribers compared to other users. The bandwidth allocation problem is formulated as an optimi-zation problem and solved by Lagrangian duality. Numerical results reveal that the optimal bandwidth allocation algorithm can differentiates the priority–based service and utilize all available resources within the network capacity. Article ID: 70084 Title: Max-Degree Network Coding for Wireless Data Broadcasting Name: Kui Xu Affiliation: PLA University of Science and Technology E-mail: [email protected] Abstract Wireless broadcasting systems employ multiple retransmissions to guarantee the correct reception of each packet. Traditional hybrid automatic retransmission request (HARQ) protocol retransmits one packet per slot. Hence, a large amount of retransmissions is required to correctly receive all the packets, which leads to low spectrum efficiency. In this paper, we propose a Max-Degree Network Coding (MDNC) based Wireless BroadCasting (WBC) protocol. Specifically, to reduce the overall number of retransmissions, lost packets of different user equipments (UEs) are network coding (NC) combined at the access node (AN) by utilizing MDNC strategy. At each UE, the lost packet can be recovered by using the proposed joint network recursive systematic convolution (RSC) decoder (JNRD). Theoretical analyses and simulation results show that the average number of transmissions performance of the proposed MDNC based WBC protocol outperforms that of the traditional index NC based WBC protocol.

Appropriate parameters can be selected in order to reduce the number of account operation and amount of signaling by omitting some credit re-authorization process. An online charging model is proposed by using the signaling procedure optimization. In the model, session based charging function is divided into six closely linked modules. Before responding to the re-authorization request caused by the change of Quality of Service, the session based charging function extracts the useful information from the request information, and then looks-up a table to calculate and select the optimal charging method.

Thus many researches are about VoD system. We notice that among all the system proposed, there are more or less space to make improvements. For example, seldom systems break the rule that one peer only transfer data with one single parent in the streaming service. As for the parent selection, most paper focus on the optimization on network topology, such as building a subset based on either content relevance or geographical features. In this paper, we gather the history information of each peer and rate each peer with the statistics, in order to select most reliable peers to play as parent peers. After the parent peer is chosen, the playing

peer downloads the necessary video data from all the parent peers simultaneously to speed up the caching process. In this way, not only the server load is reduced, the playing peer gets better quality service as well. Article ID: 70088 Title: A Dynamic Conformance Checking Method Based on Petri Nets for Satellite Communication System Network Control Protocol Name: Jun Zhu Affiliation: Nanjing Telecommunication Technology Research Institute E-mail: [email protected] Abstract For the existence of malice or abnormal nodes and the influence of unreliable satellite network environment, some violations may probably happen in network control protocol execution process, which lead to the inconformance between protocol specification and actual protocol execution states. It reflects the robustness problems in relevant protocol design issue. Meanwhile, it is difficult to assure that the interaction behaviors of protocol nodes conform to the expectation of protocol specification. To tackle the inconformance problem, this paper proposes a colored Petri nets based conformance checking method. A satellite network control protocol signaling dynamic conformance verification framework, which is used to capture runtime protocol signaling from protocol execution environment, is presented. Then, it puts forward a signaling dynamic conformance checking algorithm that centers on the protocol interaction behaviors. At last, performance and overhead evaluations are performed to demonstrate the usability and availability of this conformance checking method.

Abstract With the development and evolution of the LTE system, the operators are experiencing huge challenges on opera-tions and service maintenance, which sets off a wave of SON (Self-organizing Network) research. As one of the crucial component of SON, the cell outage detection is an effective way to automatically detect outage cells resulted from hardware or software problems. Our work in this paper aims to introduce a cell outage detection mecha-nism to timely and accurately detect outage cells. After classifying the cell into four states, namely the healthy, degraded, damaged and outage state, we present a cell outage detection mechanism based on BP network. In order to enhance the training speed of traditional BP, the Differential Evolution (DE) algorithm is adopted as the training algorithm. We have simulated the proposed mechanism in the matlab environment and get a better performance of high detection accuracy by comparing it with the standard BP algorithm. Article ID: 70090 Title: An UEP Transmission Scheme Based on Distributed Rateless Codes Name: Chen Cui Affiliation: Harbin Institute of Technology E-mail: [email protected] Abstract In this paper a new coding scheme is proposed to accomplish unequal error protection (UEP) for distributed rateless codes. This coding scheme can be applied when multi-sources symbols share a single relay and the relay has no knowledge about their importance levels. We design this coding scheme by encoding the symbols with a second LT process at the relay. UEP property is provided via several equal error protection (EEP) LT processes. Asymptotical analyses have been made on how the encoding parameters affect the error performances. Experimental results show that the second LT process at the relay significantly improve the error performances of the symbols. Asymptotic analysis and experimental results prove this coding scheme viable.

Article ID: 70091 Title: A Modified Traffic Grooming Algorithm with High Trade-Off Efficiency for Optical Network Name: Mengfei Lyu Affiliation: Peking University E-mail: [email protected] Abstract As the energy consumption of network has become an increasingly important issue, traffic grooming on Internet protocol over wavelength division multiplexing (IP-WDM) networks has been widely used for energy-efficient optical network. Traffic grooming can reduced the number of installed light paths and corresponding IP router line cards at the cost of traffic processing overhead. However, traditional traffic grooming algorithm tends to prefer longer paths, which are responsible for longer transmission hop distance. Although there are studies that focus on reducing hop distance, the energy consumption increases accordingly. In this way, the trade-off between energy consumption and hop distance is a problem worth discussing. This paper proposes a modified heuristic traffic grooming algorithm which can improve the trade-off efficiency by about 20%, compared with the earlier algorithms. Article ID: 70093 Title: Dynamic Mode Management in Cognitive Radio Networks with RF Energy Harvesting Name: Junmei Zhao Affiliation: Beijing University of Posts and Telecommunications E-mail: [email protected] Abstract In order to realize green communication, we consider a cognitive radio network where the secondary user (SU) is equipped with RF energy harvesting capability. The three-state Markov chain is used to model the primary user (PU) channel, which considers both the channel occupation information of the primary network and the channel quality information. We assume that the SU cannot execute RF energy harvesting and packet transmission at the same time. Consequently, at the


beginning of each time slot, the SU should make the decision to harvest RF energy or to transmit a packet. The mode decision depends on the channel state and the available energy in the energy queue. We formulate the mode management problem of the SU as a Markov decision process (MDP) problem that can be solved using dynamic programming. The objective of the proposed strategy is to maximize the expected number of packets successfully transmitted. Simulation results are presented to demonstrate the effectiveness of the proposed strategy. Article ID: 70095 Title: Fast Depth Map Intra Prediction Algorithm Based on Edge Detection and CU Partition Name: Zhenyong Wang Affiliation: Harbin Institute of Technology E-mail: [email protected] Abstract This paper proposed a new fast intra prediction algorithm based on fast edge detection and CU partition for depth map to reduce the coding complexity of Multiview Video Plus Depth (MVD) coding in HEVC. The latest video coding standard HEVC greatly improves the coding complexity of intra prediction because of complex coding unit (CU) partition and lots of prediction modes. Depth maps always have smooth regions separated by sharp edges. Smooth regions can help to speed up the CU partition and reduce the time of intra mode decision, and sharp edges must be protected to ensure the quality of synthetic viewpoints. In the new algorithm, an equation and a threshold T are used to detect whether there are edges in current CU. To different kinds of CU, different intra mode decision methods are taken. After simulation, the experimental results show that the proposed algorithm significantly reduces the coding times, while maintains high bitrate and PSNR performance in comparison with original HEVC algorithm.

Affiliation: BUPT E-mail: [email protected] Abstract Since user equipment (UE) has to obtain the cell identification (cell ID) and timing information to start the communication with base station, cell search is the initial step in cellular systems. The research of 5G has started to improve the performance of wireless communication. A new scenario named ultra-dense network (UDN) has been introduced and there will be more access nodes per unit area. However, with the distribution of small cells gets more complicated and the interference is stronger, cell search will be a big challenge. In Long Term Evolution (LTE) of 4G, two signals named primary synchronization signal (PSS) and secondary synchronization signal (SSS) are designed for cell search. Correct detection of synchronization signals makes UE be able to get the frame boundary and Cell ID. However, the detection accuracy will be poor when the cell density grows. Focusing on UDN scenario, we give a definition of cell cluster and design new synchronization signals. Moreover, a new cell search scheme based on the redesigned signals is presented. Simulation is conducted to evaluate the detection accuracy of the new scheme. The result presents that the performance of the new scheme is much better than the existing scheme in LTE. Article ID: 70099 Title: A Simplifed Joint Demapping and Decoding for LDPC Coded BICM Systems Name: Huang Ping Affiliation: HoHai University E-mail: [email protected] Abstract Make full use of the characteristics of LDPC decoding, Stephan ten Brink had proposed a joint iterative demapping and decoding algorithm for LDPC coded BICM systems. Based on Brink proposed algorithm, we propose a modified joint iterative scheme to further reduce the computation complex. Different from the algorithm presented by Brink, in the process of iterative demapping and decoding, the proposed method simplifies the update


calculation of the LDPC parity check nodes by adopting the UMP-BP. More importantly, to compensate for the performance degradation brought by UMP-BP, LLRs optimization based on certain optimality criterion is employed for the proposed method. Numerical analysis shows that the complexity of the proposed method is less than traditional joint iterative algorithm. Simulation results also show that by LLRs optimization the proposed method achieves noticeable performance improvement compared with the BICM-ID and the joint iterative algorithm.

In this paper, we take spectrum aggregation and collaboration relay technology together, and proposed a dynamic spectrum aggregation scheme based on energy-saving in cog-nitive relay network. Besides, through the simulation, we analysed the network performance and energy efficiency of the proposed algorithm.

Article ID: 70109 Title: Mimo Antenna for Uwb Communications Name: Joseph Jervase Affiliation: Sultan Qaboos University, Oman E-mail: [email protected] Abstract Design of ultra-wideband antennas is challenging in the stringent requirements that are often conflicting to achieve a wide impedance bandwidth while maintaining high radiation efficiency, uniform gain and compact size. A Multiple-Input Multiple-Output (MIMO) antenna system can enhance the overall antenna performance but at having to overcome new challenges such as reducing the mutual coupling and the correlation between the elements. A printed circular disc compact planar antenna is selected in this work due to its UWB performance and compact size for the MIMO antenna system. A parametric analysis is carried out to achieve an optimal design. The system developed consists of two elements with an overall size of 59×27 mm. The designed antenna system operates over the whole of the UWB bandwidth from 3.1 to 10.6 with radiation efficiency up to 85% and reflection coefficients less that –10 dB. The envelope correlation is less than –60 dB throughout the UWB band while the diversity gain approaches 10 throughout the entire UWB bandwidth and Total Active Reflection Coefficient (TARC) between the antenna elements is less –11. Thus the proposed MIMO antenna outperforms similar antenna systems reported in the literature. Article ID: 70110 Title: Heuristic Optimizing of PCI Assignment in


Real-life LTE Networks Name: Wu Songrui Affiliation: Beijing University of Posts and Telecommunications E-mail: [email protected] Abstract Assignment of Physical Cell Identity (PCI) is an important work in TD-LTE network optimization, and the reasonable PCI allocation helps to eliminate the interference and improve the quality of service of networks. In the practical large-scale TD-LTE networks, how to properly reuse PCIs among a large number of cells is challenging. In this paper, we propose a multiobjective optimization model for PCI allocation. This model aims to minimize both the interference and the number of the cell pairs violating soft constraints while maintaining the hard constraints being satisfied. We present a heuristic solution to this optimization model. This heuristic scheme uses the maximum spanning tree to determine the eNodeB order, and then following this order, assigns the available PCIs to each eNodeB’s cells in a step-by-step manner. We applied the heuristic scheme to adjust the PCI configuration of 1233 cells in the real-life TD-LTE network in Zhuhai city, Guangdong Province, China. From the interference and constraint viewpoints, the optimized PCI configuration is evaluated and compared with the original configuration. The evaluation results demonstrate that the proposed heuristic scheme considers several constraints and is an efficient approach to PCI optimization in large-scale and real-life TD-LTE networks. Article ID: 70112 Title: The Effect of Phase Shifter Errors on The Performance of Millimeter Wave Beamforming Name: Junlin Tang Affiliation: UESTC E-mail: [email protected] Abstract Due to the cost and power supply, RF beamforming using low precision phase shifter is always used in milli-meter wave instead of baseband beamforming. In IEEE 802.11.ad, beamforming is based on a codebook by 2 bits

phase shifter, which degrades the link performance. This paper analyses the performance loss due to the limited precision of phase shifter and simulation is performed to validate the result of analysis. At the same time several conclusions are obtained: (1) with the increase of the accuracy of the phase shifter, the performance of beamforming is improved which is reflected in the side lobe suppression and main lobe improvement; (2) The gain loss brought by the low pre-cision phase shifter is limited, a 3bits phase shifter can get a close performance to the ideal one. So precision of the phase shifter is not the key factor that affect the performance of millimeter wave beamforming. More attention should be focused on other aspect, such as the channel estimation, acquisition of optimal beamforming weights, etc. Article ID: 70114 Title: A Time Synchronization Scheme for Sensor Networks Based on Ant Colony Algorithm Name: Wei Nuo Affiliation: Shandong Computer Science Center E-mail: [email protected] Abstract Time synchronization has received a great attention as its crucial parts in wireless sensor networks. To minimize the number of transmission packets and achieve energy efficiency, a time synchronization scheme based on ant colony algorithm (TSAC) is presented in this paper. By exploiting the principle of ant colony algorithm adjusting the pheromone dynamically and automatically, an optimum pair selection theme is designed to select the nodes synchronized by performing the pairwise synchronization, and all the other nodes could be synchronized by listening. The simulation results show that TSAC needs less message exchanges and provides more accuracy than other time synchronization algorithms.

Affiliation: Department of Electronics and Information Engineer E-mail: [email protected] Abstract In digital signal processing, it is difficult to achieve flexible arbitrary sampling rate conversion. As for this problem, a new algorithm is proposed to realize arbitrary variable up-sampling based on lookup table. The algorithm firstly constructs an original filter whose coefficients are stored in ROMs. Then the target filter is decimated from lookup table by mapping sampling rate as address. Arbitrary variable up-sampling can be achieved when input signal passes through the target filter after zero-insertion. The paper describes principles of the algorithm and constructs the model, then proves the validity of the scheme, and analyzes the performance as well as the effects of errors. The results show that the proposed algorithm has better performance than conventional algorithm and the effect of errors is negligible. It can implement arbitrary variable up-sampling speedily and conveniently within a certain range.

We proposes a method that we use the BP network to com-press at the sending end, and then save the weight. The method reconstructs data in the terminal, which greatly reduces the amount of data in real-time transmission to ensure the fast and effective of real-time positioning. The used simulation environment is in the 27 AP in the floor for data acquisition and real-time simulation application. The applied algorithm is a universal KNN algorithm. The core data compression

method is the improved BP neural network. Finally, focusing on the data in the input end of BP network, the paper makes the real-time Radiomap be normalized and presets the simulation parameters. The simulation results show that in the case of choosing ap-propriate parameters to simulate, compared to the RAR compression it can compress the whole Radiomap in to 1/2 or even 1/3 of data size, it can maintain high stability in a certain degree of compression, and it can guarantee the reconstructed and compressed data has lossy compression within the allowable range of positioning accuracy. Article ID: 70120 Title: A Limited Feedback-Based Bit Allocation Method For Interference Alignment Name: Hui Dun Affiliation: Harbin Engineering University E-mail: [email protected] Abstract While distract interference alignment needs ideal channel state information (CSI), this is difficult to achieve in real communication system. But reality communication system possesses feedback link. Based on this, interference alignment (IA) with limited feedback was proposed. Channel coefficient matrices is quantified at receivers, and then the precoding matrix will be designed with the quantified channel coefficient got in feedback scheme at transmitters. Then interference alignment can be achieved when perfect channel state information is not available. Consider the rate loss of the system caused by limited feedback, and the rate loss under the method of bit average allocation for interference alignment with limited feedback isn’t minimum, a new bit allocation method is proposed. The proposed scheme can improve the rate performance due to the rate loss is reduced. The simulation results showed that when the condition of interference alignment is satisfied, the proposed method can improve the sum rate of the system compared with the traditional interference alignment with limited feedback method. Article ID: 70122 Title: Social-Aware Hierarchical Multicast In Mobile


Delay Tolerant Network Name: Wenhua Yin Affiliation: Inner Mongolia University E-mail: [email protected] Abstract With the popularization of portable devices equipped with wireless communication capability, Mobile Delay Toler-ant Network (MDTN) gets extensive attention of scholars. Infrastructureless networking with portable devices has become a typical scenario in MDTN. With regard to the infrastructureless MDTN scenario composed by portable devices, we propose a social-aware hierarchical multicast distribution algorithm (SAHM) which is suitable for this scenario. SAHM algorithm regards community detection, centrality computation and the prediction of contact rate. The community structure in the network is identified by K-Clique algorithm. On the basis of communities, we de-termine whether the meeting node can act as a relay node based on the C-Window centrality and the contact predictability. Intercommunity SAHM selects relays among those nodes whose contact rate is higher and higher than Pthresh. Intracommunity SAHM selects relays among those nodes whose C-Window centrality is high. In order to verify the performance of SAHM algorithm, we implement SAHM algorithm on the ONE simulation platform and compare whose performance with the existing classical algorithm on two real data sets (Infocom06 and Cambridge). Simulation results show that our proposed algorithm has similar data delivery ratio with the existing algorithms or higher than them, but significantly reduces data forwarding cost, making data more quickly and efficiently forward to the nodes which need data.

The secondary user (SU) uses this threshold to detect whether the spectrum is occupied by the primary user (PU) or not. Three specific NLOS scenarios are depicted and analyzed in this paper. In order to improve the existing threshold value in energy detection for a LOS environment, we need to consider the specific path loss through different obstacles. Different path loss exponents are considered to represent different obstacles and used to calculate the path loss. The improved threshold value is then obtained based on the updated path loss. Computer simulations demonstrate our proposed method.

Abstract In this paper, we proposed an image denoising filtering method based on PCNN(pulse coupled neural network) for images polluted by the pulse noise. The method firstly determined the position of pixels polluted by noise ac-cording to the fire capture features of PCNN. Then, a sim-ilar median filtering step was applied on the processing of noised pixels. Finally, the iterations and the sizes of filter window were chosen according to the noise intensity, which realized the adaptive-filtering of images. The main result states that, compared to mean filtering, median filtering and adapted-median filtering, the method we proposed was not only effective in denoising and keeping details of images, but also showing good performances in different SNR conditions.

In the hybrid algorithms, iBeacon divides the space into different parts, with the combined iBeacon and Wi-Fi offline fingerprint data, then it locates partly. Compared to the single Wi-Fi indoor positioning algorithms, it can significantly reduce the amount of calculation and the error of positioning. Article ID: 70132 Title: Joint Channel Network Coding For Correlated Sources Name: Youssef Zid Affiliation: Sys’COM Laboratory National Engineering School of Tunis, Tunisia

E-mail: [email protected] Abstract In this paper, we consider a Generalized Joint Channel Network Coding (GJCNC) applied to Physical Layer Network Coding (PLNC) for Two Way Relay Channel (TWRC). For this purpose, two correlated sources A and B desire to exchange information with each other by the help of a relay R. PLNC allows the relay to decode the combined information of both sources from the superim-posed information. A Low Density Parity Check (LDPC) code is used as a channel code. A new design of GJCNC is developed by exploiting the correlation between nodes. Since the relay doesn’t know in advance the correlation between sources, an estimation of this quantity must be applied. Simulation results show that the Bit Error Rate (BER) can be significantly decreased by exploiting this correlation. In addition, a lower number of iterations is necessary to achieve a desired BER in comparison with a classical scheme which doesn’t exploit the correlation between sources.

The antenna is compatible with WiMAX and WiFi standards. After reviewing a couple of literatures,

the antenna was designed, analyzed and proven for two central frequencies, 2.5GHz and 5.6GHz, with much improved bandwidths. Finally, the antenna was manufactured with the overall size of 4cm×4.4cm on Rogers (RO4003) substrate. The antenna is made into three L-shaped radiators.

Article ID: 70143 Title: Experimental Study on Wireless Interference in RFID System Name: Yang Fu Affiliation: Beijing University of Posts and Telecommunications E-mail: [email protected] Abstract The objective of the proposed work is to find the effects on the reading performance of 900 MHz radio frequency identification system (RFID) under the wireless interference. Experiments were carried out in full anechoic chamber avoiding the influence of wireless signal produced by the reflection. In order to simplify the analysis of the process of performance, single tone signal was selected as the source of wireless interference. The performance was measured in terms of change in the successful reading rate of tags and the interrogation range of the reader. Typically the performance of the RFID will decline due to the wireless interference. However in our experiment it was found that the unwanted signal can significantly improve the performance of RFID system when its power reach a certain range. To explain this phenomenon, we analyze the tag circuit as well as the back-scatter link, and the ratio m was defined to characterize the degradation of reading performance. It was concluded that the results we calculate using the method we proposed was matched with the experimental results. Article ID: 70144 Title: A Invulnerability Assessment Based on Importance-Degree of Node for Weighted Network Under Attack with Partial Information Name: Lu Xiangqun Affiliation: Beijing University of Posts and Telecommunications E-mail: [email protected] Abstract We study invulnerability of complex networks subject to attacks on nodes and links. For the purpose of precisely assessing invulnerability of complex networks, in this

paper we proposed a invulnerability assessment on the basis of importance-degree and partial attack information by measuring two metrics of network invulnerability, robustness and efficiency. We defined the term of importance-degree to describe importance of different nodes in the networks. We form a probability model to describe the process of acquiring information under three types of attacks, random attacks, partial information attacks and intentional attacks, and simulate the process of acquiring partial information by sampling nodes in accordance with the probability model. The simulation results contain that weighted networks hold strong invulnerability to random attacks, whereas they are extremely fragile when suffering those intentional attacks; more information is exposed, less invulnerability networks display, especially complete information attacks which are the same with intentional attacks that all information of nodes or links would be acquired by assailants; the more important information is acquired, the more quickly network invulnerability decreases.

The performance of real CDMA-OFDM/OQAM transmission system with Walsh Hadamard spreading code is directly linked to the performance of OFDM/OQAM system. OFDM/OQAM performs better than CP-OFDM and


CDMA-OFDM/OQAM outperforms conventional MC-CDMA thanks to the no use of the Cy-clic Prefix and the good choice of the prototype filter. We present the simulation results of the performance of OFDM/OQAM system with Isotropic Orthogonal Trans-form Algorithm (IOTA) prototype filter compared to con-ventional CP-OFDM system and the performance of the combination CDMA-OFDM/OQAM compared to MC-CDMA. The performance is derived by computing the Bit Error Rate (BER) as a function of the transmit signal-to-noise ratio (SNR). Article ID: 70147 Title: Adaptive Energy-Efficient Configuration of Power Resource for Ofdma with Opportunistic Df Relaying Name: Li Feng Affiliation: UESTC E-mail: [email protected] Abstract In this paper, adaptive power allocation (PA) on the source and relay is investigated to maximize energy effi-ciency (EE) for OFDMA opportunistic DF links (O2RL). We derive EE function from O2RL model by appropriate definition of variables to represent source/relay PA, sub-carrier transmission mode selection (STMS) elegantly. Theoretical analysis demonstrates that EE function for O2RL is strictly quasi-concave with respect to the overall transmit power. Exploiting the quasi-concavity property of the EE function, an EE-oriented optimal PA iterative method for O2RL is proposed which used the bisection method to speed up the search of the optimum. Simulation results demonstrate that the O2RL is more energy-efficient than traditional cooperative relaying strategies (TCRS), and the proposed method as compared to the sum throughput maximization PA method (STMPA) is able to significantly improve performance in terms of system EE.

Affiliation: Academy of Equipment E-mail: [email protected] Abstract The micro-Doppler effect on a flying spinning target, in-troduced by the rotation, would modulate the receiving signal with SFM (Sinusoidal Frequency Modulation), that we usually use some TF (Time-Frequency) analysis meth-ods with complex calculation to estimate the frequency. As to the issue of the complexity of the classic TF method, a method based on the piecewise FFT was proposed in this paper. With the analysis of the local stable properties of SFM signal, the selection of the segments M and its influence on the performance of frequency estimation was discussed. Then we divided the signal into M seg-ments with FFT, and corrected the frequency offset caused by the fence effect. And the calculated amounts of this algorithm was analysed. Finally the piecewise FFT was verified to be less calculated amounts and easy to implement with a better SNR which could be applicable to the processing of cooperative target by simulation. Article ID: 70152 Title: Design of Wide Stopband Filter with Tunable Center Frequency Name: Zhaoqing SUN Affiliation: Harbin Engineering University E-mail: [email protected] Abstract A dual passbands filter with the function of varactor tuned is proposed in this paper, which has a wide stopband. Stepped impedance resonators (SIRS) is used at the filter. The varactor is loaded on the T-shaped resonators, while changing the bias voltage across the varactor, The second passband frequency is tuned from 1.56GHz to 2.25GHz; the first passband’s center frequency is fixed at 1.02GHz and maintained though out the simulation. The first passband bandwidth is 14.7%, the insertion loss value is 0.2dB and the value of the return loss is 19dB. The second passband is tuned between 1.56 GHz and 2.25GHz where the tuning range is maintained at 36.2%, relative bandwidth remains unchanged. The insertion loss changes from 0.2dB to 0.8dB while the return loss shift from 16dB


to 30dB. The propose filter achieves a great harmonic suppression characteristic of -20dB up to 5GHz. The designed filter has two advantages, one is that to depress stopband, the filter network is incorporate in the output input coupling line, the other advantage is that the performance of the filter is optimize by adding spur lines (spurlines) at the input and output coupling line which is useful to increase zero between the two passbands. The proposed filter is compact in size, has low insertion loss, wider rang harmonic suppression and is efficient compared to other filters. Simulations show that the filter proposed is valid and has a good performance. Article ID: 70153 Title: Manifold Locally Linear Denoising for Wi-Fi Rss Based Indoor Positioning Name: Gang Shen Affiliation: Huazhong University of Science and Technology E-mail: [email protected] Abstract In this paper, we investigate the problem of locating the indoor objects with the help of the received Wi-Fi signal strength fingerprints. Many Wi-Fi RSS based positioning techniques have been developed recently for indoor posi-tioning purposes, but the positioning accuracy faces many challenges, including the high noise to signal ratio. In this paper, we consider two remarkable elements affecting the positioning performance: the slow attenuation of the sig-nal strength, and the large measurement noise. We pro-pose a novel approach to locating a target object in a given area by introducing a denoising algorithm based on the local linearity of the signal-location manifolds. This is implemented with a fixed set of linearization weights de-termined not by the signal values but by the relationships of the locations of the fingerprint samples. We also ex-plore the relations between the prediction error and the manifold curvature, the number of APs used for position-ing, and the signal noise level, characterizing the quality of the nearest point estimation with the signal measurement errors. A simple algorithm is presented to locate the target using the k-nearest neighbors in the signal space. Simulations in

various settings demonstrate the effective-ness of the proposed approach. Article ID: 70154 Title: Traffic Flow Assignment with Weight for Resource Allocation on The Restorable Network Name: Shin-Jer Yang Affiliation: Dept. of Computer Science and Information Management, Soochow University, Taipei, Taiwan E-mail: [email protected] Abstract Let G(N, L) be a network with n nodes and m links such that each node u has a weight w(u) and each link e has a flow upper bound fu(e) and a flow lower bound fl(e). Consider the situation where many source-destination s-d routing paths exist over the network G. If some link e has failed, then the routing path through e must be rerouted accordingly. The rerouting and recovery will be performed by one of the two owners of the path and the network G must be restorable from the link failure quickly. We propose an efficient and heuristic FARN algorithm for solving this problem and alleviating congestion control on the TCP/IP-based networks. Then, we can utilize the FARN with Greedy Heuristics algorithm to effectively tune and adjust the flow assignments of each link. Also, we make performance simulations to obtain better performance on the IP-based MANET. Meanwhile, we can employ our pro-posed FARN scheme to real-time system and solve QoS issues of links between clients and servers on the Cloud computing.

So, in order to deal with SSDF, an improved hard-decision fusion algorithm was proposed, which adopts the mechanism that FC just fuses parts of results reported by CUs preferentially and the remaining users take supplement for decision in order to reduce the opportunities for MUs to take participate in the cooperation. Besides, through comparing the CUs’ reputations updated according to their history behaviors, FC selects reliable users’ data to fuse with the object of ensuring the reliability of the data.

In the single node sensing, we research the change of p values which has impacted on system performance under certain signal to noise ratio and obtain the optimal p values making the Bayes risk minimum. In the cooperative spectrum sensing, we use &quot;K-out-of-N&quot; rule and when the rule of K is a certain value, research the change of p values impact on the system performance, as well as the effect of system performance by changing K values.

In this paper, the process of determining the location of the nodes is divided into three stages which are initialization, localization and optimization. In stage of initialization, considering the location method simulation of distance

In stage of localization, to improve the network location accuracy, the local search algorithm is adopted to select the optimal combination of the known nodes, and use the least square principle to calculate the unknown nodes’ localization. In stage of optimization, weighted centroid algorithm is adopted to estimate the unknown node location in which weights come from multiple sets of Geometric Dilution of Precision(GDOP). Simulation results verifies that the presented method can significantly improve the network coverage and location accuracy.

Multi-Feature Weighted Appearance Model Name: Bai Meijuan Affiliation: Taiyuan University of Science and Technology E-mail: [email protected] Abstract Visual tracking is a hot but challenging research direction in computer vision field. The appearance of target changes continuously over space and time, which makes it difficult to develop a robust and efficient tracking algorithm. Most existing tracking algorithms describe the target with single feature which may make the tracker easily influenced by various intrinsic and extrinsic changes and even lead to trace failure. In this paper, in order to describe the complex changes of the target and background in real scene more accurately and to improve the flexibility of statistical model, an effective and efficient tracking algorithm is proposed based on an appearance model of weighted multiple features extracted from blocked images in the compressed domain. Two complementary matrices are generated to measure multi-dimension intensity and texture features. Mahalanobis distance is employed as the weights of the various features. Then a naive Bayesian classifier is utilized to make a binary classification for the candidates. A coarse-to-fine search strategy is adopted to reduce the computational complexity. Experimental results demon-strated that the robustness and accuracy of our algorithm are greatly improved compared with several state-of-the-art tracking algorithms.

This paper presented the interface-aware LDPC codes in the millimeter-wave system to support high-speed Ethernet interfaces and reduce the conversion delay. Con-sidering constraints of the encoded codeword length of 1G to 100G Ethernet physical layer, LDPC(196, 120), LDPC(588, 528), LDPC(1197, 1089) codes on the basis of 1G, 10G and 100G Ethernet interface were designed to reach low latency in the channel coding process. The sim-ulation results claimed that the interface-aware LDPC codes have an excellent performance and the minimum processing delay in the system, taking encoding delay and decoding delay into consideration. The encoding delay of 0.58~1.17us and the decoding delay of 3.20~4.26us could meet the code rate for the different channels in Ethernet interfaces. Article ID: 70169 Title: A New Frequency Estimator of Sinusoid Based on Interpolated FFT Name: Lei Fan Affiliation: Dalian Maritime University E-mail: [email protected]

Abstract A new frequency estimator of sinusoid based on interpo-lated FFT amplitudes is proposed. Firstly, zeros of length N are padded to the sinusoid sampled data of length N in the time domain. Next, 2N-point FFT is performed and the coarse estimation is made by searching the location of the spectrum line with maximum amplitude. Finally, the fine estimation is made by utilizing the amplitudes of the spectrum line with maximum amplitude and its two neighbors. Simulation results show that the root mean square error of frequency estimation of proposed estimator is close to the Cramer-Rao Lower Bound when the signal frequency locates anywhere between two neighboring FFT spectral lines. The proposed method has low computation complexity and outperforms the existing estimators.

Article ID: 70178 Title: Sparse Fourier Transform Based Millimeter Wave Wideband Spectrum Sensing Name: Meili Na Affiliation: Shanghai Institute of Microsystem and Information E-mail: [email protected] Abstract This paper presents a wideband spectrum sensing methods based on the sparse fast Fourier transform applying for E-band, which can capture spectrum in real-time without sampling the signal at the Nyquist rate. Our approach builds on recent advances in the area of sparse Fourier transform. At first, we convert the signal of E-band to the baseband, and then sample the wide baseband signal at a low sampling rate, obtaining a small subset of the original signal samples. Finally the spectrum of the wideband signal is recovered using the sparse Fourier transform. The required sampling rate can be reduced to about 10% of the conventional FFT methods required. Meanwhile, it improves operational efficiency, and makes it possible to sense in real-time. MATLAB is used to demonstrate the

feasibility of this design. This algorithm has an extremely low rate of false negatives when the spectrum occupancy is sparse and proposes solutions even in scenarios where the spectrum is not sparse. Article ID: 70180 Title: Power Allocation Optimization for D2D Communication Underlaying Cognitive Full Duplex Relay Networks Name: Long Liu Affiliation: Beijing University of Posts and Telecommunications E-mail: [email protected] Abstract This paper investigates the joint use of full-duplex relay (FDR) and Device-to-Device (D2D) communication in cognitive wireless networks (CWNs). FDR not only in-creases the time-frequency efficiency by the time-frequency reuse compared to half-duplex relay (HDR), but also expands the network coverage by the use of the relay. In addition, D2D can enhance the wireless resource efficiency and achieve high data rates and network throughput. In the paper, we use jointly D2D and FDR to propose a new CWN model, in which the D2D link under-lays the FDR link in secondary networks and D2D trans-mitter is arranged as a FDR node to assist the transmission between secondary users. Then we optimize the rates of the D2D link, namely improve the secondary network throughput by the transmission powers allocation of the secondary transmitter and the FDR node in the case that the good FDR link communication situation in secondary networks is guaranteed and the secondary network doesn't interfere the primary network. The simulation re-sults demonstrate that the proposed D2D communication underlaying cognitive full-duplex relay network outper-forms the traditional CWNs and ones applying HDR and D2D in the secondary network throughput.

Article ID: 70185 Title: An Implementation of Multi-domain Software Defined Networking Name: Zhengxin Guo Affiliation: Beijing University of Posts and Telecommunications E-mail: [email protected] Abstract Software Defined Network (SDN) is an emerging archi-tecture which can simplify network management and enable innovation through network programmability by decoupling the control plan and the data plan of the network. However, traditional SDN architecture is not suitable for all cases, a single controller may become a performance bottleneck in a wide area network. While current multiple controller solutions always make the

network more complex and harder to be managed than traditional SDN network. In this paper, we proposed a new architecture for multi-domain software defined networks, which divided the control platform into two layer vertically. The bottom layer consists of local con-trollers, which only has the knowledge of the local do-main it controls. And the top layer is coordinating con-troller controlling all local controllers. The communi-cations between local controllers and coordinating controller use a standard NBI as communication proto-col which is also the protocol used when controllers (both local controllers and coordinate controllers) communicate with applications. We implemented the architecture and our evaluations show the feasibility of it.

Abstract Nowadays, multi-hop communication systems are often applied in power transmission system to transmit surveillance information to control center. In order to transmit surveillance data more efficiently, it is required to design the communication system with low latency and high reliability. This paper provides a novel data transmission framework along with a QoS provisioning multi-hop routing scheme for in smart grid. During normal data transmission period, all the nodes along the power line are divided into two groups.

To avoid the wireless interference, we allocate the spectrum among these sensors and minimize the number of sub-channel. When urgency occurred, node with the emergency information can select a relay node within its maximum transmission range according to the delay requirement. The simulation results are given to show the efficiency of our data gather framework.

Mobile Cloud Storage Name: Hui Li Affiliation: School of Computer Science, Beijing University of Posts and Telecommunications E-mail: [email protected] Abstract In order to avoid data loss when user’s mobile device is stolen or lost, users are encouraged to use mobile cloud storage to transfer and store the data from mobile termi-nals to the cloud as a means of data backup. Although various encryption mechanisms have been proposed to protect the security in cloud side by cloud service provid-ers, the traditional cloud systems still cannot persuade the users that the data are securely protected if the secure mechanisms are not implemented by the user side. To prevent cloud service providers from leaking personal information, a security scheme implemented in the client side for mobile cloud storage with the name of UMCloud is proposed, the proposed scheme adopts a comprehensive mixture cryptosystem to provide protection of confidentiality and integrity for the storage of data in the cloud while supporting the sharing of the encrypted data among authorized users.

First, we make a contrast of the coverage range of TD&LTE uplink and downlink in ordinary situations. Then we calculate the 2G/3G/4G overlapping coverage lengths. Finally, we consider effective cover radius, the distance and grazing angle between stations and railway in 2G/3G/4G networks, calculate different distance between stations. The result shows that distance between stations is limited by LTE on sharing station address. Using single RRH with two antennas, the antenna height is 30m, and the speed of the train is 250KM/h, the RRH distance among different cells can be 1177m, and the RRH distance among same cells can be 1311m. As the reference of network planning, construction and optimizing, the coverage radius and station spacing in different standards calculated by this article will improve user perception and promote the brand value of China Mobile network.

In this paper, we first propose a cognitive radio networks model with motional users, while MU and SUs are made up of an approximation centralized cooperative sensing networks. The motional users include two SUs and a MU. When MU and SUs move in the certain range, MU could attack SUs heavily by adjusting its transmission power real-time. According to the proposed model , a PUEA scheme with motional users will be verified based on different HDF (Hard Decision Fusion).

Technology, Nanjing Forestry University, Nanjing, China E-mail: [email protected] Abstract In Rechargeable Wireless Sensor Networks(R-WSNs), it is critical for higher data collection rate because sensors have to operate in a very low duty cycle owing to sporadic availability of energy. Therefore, surplus energy of a node can be utilized for strengthening packet delivery efficiency and improving data collection rate for all sensors.

Through extensive simulation and experiments, we demonstrate our algorithm is efficient to maximize data collection rate in rechargeable wireless sensor net-works. Article ID: 70216 Title: Robust Device-free Fall Detection Using Wireless PHY Layer Information Name: Guo Liu Affiliation: Wuhan University of Technology E-mail: [email protected] Abstract Fall is one of the main threats to the safety of the elderly living alone. However, the traditional fall detection systems, such as video-based or wearable-device based systems, are either intrusive to their daily life, or fragile to the ambient environment. Recent systems leveraging wireless Channel State Information (CSI) can avoid such drawbacks; however, most of them have not fully taken the dynamic environment factors into account, which makes them un-robust and hinders them from being applied in practice. In this work, we propose a robust and unobtrusive fall detection system using off-the-shelf Wi-Fi devices which gather fluctuant wireless signals as indicators of human actions. Specifically, we adopt a lightweight classifier to eliminate the "bad antennas" in CSI so that we can extract features from the best CSI stream; by which, the negative effects aroused by the dynamic surroundings can be removed. We also design a novel method to intercept the valid segment of signal of fall action by utilizing wavelet analysis and dynamic time window.

Finally, we implement a full robust device-free fall detection system based on the proposed novel methods. Experimental results show that our system is robust to the complex indoor radio frequency environments and achieves good performance.

Conventional DFT-based channel estimation methods encounter performance degradation due to low SNR and the edge effect caused by virtual subcarriers. Adding


virtual carrier frequency responses (VCFR) properly at receivers is proved to be able to effectively mitigate edge effect. The proposed method adopts the VCFR addition method into practical downlink LTE systems to alleviate edge effect. A novel noise eliminating strategy based on energy detection is demonstrated in the proposed method to improve the overall performance especially in low SNR scenario. Compared with existing DFT-based channel estimation methods, simulation results of the proposed channel estimation method showed a relatively lower Mean Square Error (MSE) and raw Bit Error Rate (BER) under several kinds of standard channel models within wide SNR range. The proposed method is also proved to have roughly the same level of complexity as conventional DFT-based channel estimation method.

On the whole, the improvement can obtain higher localization accuracy than the original method while the network topology and beacon proportion are variational.

Article ID: 70227 Title: A New Noise Mitigation Method Based on Normalization Time Frequency Peak Filtering in Broadband Power Line Communication System Name: Zhigang Qiu Affiliation: Yuncheng Power Surpply Company E-mail: [email protected] Abstract In the power line communication system(PLC), due to the commercial PLC modems feature low power transmission and the large amount of noise, the communication system has a very low signal to noise ratio(SNR) which seriously affects the reliability of the signal transmission. Considering the situation of low SNR, this paper presents a noise mitigation method based on normalization time-frequency peak filtering(NTFPF). NTFPF is a signal enhancement method based on the principle of instantaneous frequency estimation and signal normalization. In NTFPF, the observed noisy signal is


firstly normalized and transformed to be processed into instantaneous frequency (IF) of the analysis signal by frequency modulation, and then the peak of time-frequency distribution of analysis signal is taken as the estimation of IF for the concentration of time frequency distribution of analysis signal along with IF. Numerical experiments have shown that the NTFPF method has a good performance in PLC system at low SNR.

Name: Jincheng Zhao Affiliation: Beijing university of Posts & Telecommunications E-mail: [email protected] Abstract In the existing distributed cooperative spectrum sensing schemes, cooperation based on consensus algorithms is a research hotspot. However,the existing methods haven’t embody the reliability difference among cognitive radio users, so there is an enormous scope to improve the accuracy. In this paper,we propose a weighted average consensus-based distributed compressive spectrum sensing (PE-WDCS) using prior parameter exchange. In this scheme, every secondary user (SU) recovers its local wideband signal with bayesian compressive sensing method,and then conducts information fusion with proposed weighted average consensus algorithm and finally obtains the wideband signal. Simulation results show that proposed algorithm has significant improvement compared with the existing approaches in the accuracy of wideband spectrum sensing.

Simulation results show that there always have the optimal point in different fusion rules. Cognitive radio network design based on energy efficiency consideration is feasible. Article ID: 70244 Title: Spectrum Allocation based on Clustering in Femtocell Networks Name: S.Y. Zhou Affiliation: Key Laboratory of Mobile Communication in Chongqing University of Posts and Telecommunications, Chongqing E-mail: [email protected]


Abstract Aiming at allocating resources to eliminate inter-femtocell collision interference, a spectrum allocation strategy SAC (spectrum allocation based on clustering) for OFDMA (orthogonal frequency division multiple access) downlink femtocell networks was proposed. In SAC, a cluster was taken as the unit for frequency reuse among femtocells and the FGW (femto gateway) was responsible for clustering and resource allocation. At first, the FGW constructed an interference graph by mapping femtocells onto vertices and interference collision relationship between femtocells onto edges in the graph; then, according to the degree and saturation degree of vertices, femtocells connected in the graph were divided into different clusters; finally, the FGW assigned different available spectrum to each cluster. Simulation results show that compared to UFR (universal frequency reuse), SAC provides higher average user spectral efficiency and lower network outage probability. The increment of FBS (femto base station) number leads to the reduction of network per-formance but it has less impact on SAC than UFR. Article ID: 70246 Title: Online Anomaly Detection on Electronic Commerce based on Variable-Length Behavior Sequence Name: Weihui Zhu Affiliation: National University of Defense Technology E-mail: [email protected] Abstract User behavior-based anomaly detection is currently one of the major concerns of system security research. For e-commerce, this paper proposes an online anomaly detection method, based on variable-length sequences of user behavior. The algorithm includes a training stage and a detection stage. In the training stage, we mainly use the variable-length sequences to represent the correlation be-tween the contiguous operations, and also the correlation between the related items. It makes the representation ability of our model stronger. In the detection stage, in consideration of the legitimate user’s behavior patterns likely having a deviation from normal behavior patterns and the illegitimate user’s behavior

patterns likely being consistent with normal behavior patterns in short time, we use a windowed smooth approach to avoid such problems affecting the result when the decision value is calculated. Meanwhile, we calculate the IDF-value of every pattern in the normal user behavior pattern database, and then the pattern whose IDF-value is below the threshold would be ignored in the detection stage (The lower the IDF-value, the lower the degree of recognition). Experimental results show that our algorithm can detect anomaly in real time effectively, and could meet the needs of real-time process both in accuracy and speed.

Article ID: 70252 Title: High Rate Transmit Diversity Assisted Space Shift Keying Modulation over MIMO Channels Name: Yuanchao Han Affiliation: University of Electronic Science and Technology of China E-mail: [email protected] Abstract Abstract—Space shift keying (SSK) modulation is a newly emerging transmission technology for multiple-input multipleoutput (MIMO) wireless systems. In this paper, we propose a novel high rate transmit diversity assisted space shift keying (HT-SSK) modulation scheme to achieve the transmit diversity gain over SSK system with high spectrum efficiency. We first apply antenna shift method at each time slot to achieve transmit diversity with L time slots. Then, we use the different transmit signal combinations of L time slots to convey the additional n log2 cL information bits, where c is the number of transmit symbols in total. Thus, the proposed HT-SSK modulation scheme achieves higher spectrum efficiency than conventional transmit diversity assisted space shift keying modulation scheme, while achieves the same transmit diversity gain with small performance loss. Simulation results show that the proposed HT-SSK scheme provides significant performance gain than SSK modulation scheme with the same spectrum efficiency. It also outperforms the conventional spatial modulation (SM) scheme.

China E-mail: [email protected] Abstract In this paper, an SLNR based cascaded interference align precoding algorithm is proposed according to the study on interference suppression in downlink coordinated multi-point transmission system. In this algorithm,


cascaded precoding is adopted rather than delivering channel state information (CSI) among cells to deal with inter and inner cell interference stage by stage. In the first stage, interferences from different cells are aligned to the orthogonal space of receiving matrix of the expected cell, so that interference to the expected cell can be avoided. In the second stage, SLNR precoding is adopted to suppress the interferences among users within a cell. Simulation results indicate that the proposed algorithm improves the system capacity, reduces the bit error rate, and overcomes the limitation that the amount of online users within a cell.

The spectrum holes occur while all the signals in wide band are detected and separated. This paper focuses on the multi-signals separation problem while the signal number is uncertain and the noise floor spectrum is non-flat. The wideband spectrum is recursivelydivided into smaller scale spectrums until all the signals in wide band is detected and separated. A FSM is built with six states from the energy characteristic of signal spectrum sharp to detect and separate a single signal, and detection processing is transitions of the state. The signal can be detected and separated by FSM. At last, the simulations and experiments validate the study. Article ID: 70258 Title: Downlink Channel Estimation Based on Block-Structured Compress Sensing for Multi-Cell Massive Mimo Systems Name: Yaojiang Yu Affiliation: Key Laboratory of Universal Wireless Communications, Beijing University of Posts and Telecommunications

E-mail: [email protected] Abstract This paper addresses the problem of channel estimation in multi-cell massive MIMO systems. The channels as observed different antennas in the same cell have approximately sparsity and common support, and the sparsity and common support properties draw more and more attentions when it comes to the efficient estimation of large number of channels in massive MIMO systems. The short channel coherence times limits the upper length of the pilot sequence used for channel estimation. So it is impossible to allocate the unique pilot sequence for the different users in all the cells and the pilot sequence is reused in different cells which results in pilot contamination. To avoid the pilot contamination in multi-cell, we use the hadamard matrix to orthogonalize the pilot in adjacent cell. The coordinated approach improves channel estimation and eliminates the pilot contamination in adjacent cell. Extensive simulation results are provided to demonstrate the performance of the proposed algorithms.

Many disastrous earthquakes usually cause the loss of lives and properties over the years. Therefore, how to design a series of preventative measures and reduce the risk of damages caused by earthquakes is an important issue. So far we still do not have a better way to get earthquake warning immediately.

The EQ-system is divided into hardware part and software part. The hardware part is a G-sensor for detection. Software part is a library of earth-quake early warning called LibEQ. LibEQ combines sev-eral theories such as Support Vector Machine, Fuzzy In-ference and so on. We can build a biggest earthquake detection network with low cost. People can get earth-quake alarm by APP. Consequently, for earthquake early warning, EQ-system can produce the best possible results.

Many location management methods have been proposed and they could be classified into several categories: the distance based method, time based method, and movement based method.These methods only consider the mobility of UEs. When the telephonic traffic increases, the performance of these methods may decrease significantly. In this paper, we propose an efficient schemewhich treats user's telephonic traffic as an essential factor to allocate a proper tracking area(TA) code for a specific UE. Using parameter estimation to estimate telephonic traffic and fuzzy logic controller decide size of tracking area. With these methods we can find a TA allocation strategy to minimize the signaling cost of paging and TAU (Tracking Area Update). Article ID: 70264 Title: A Step Further of Pdr-Based Jammer Localization through Dynamic Power Adaptation Name: Qiping Wang Affiliation: College of Communications Engineering, PLA University E-mail: [email protected] Abstract


To apply further anti-jamming methods efficiently, re-searchers have proposed many jammer localization schemes in recent years. Among them, Packet Delivery Ratio (PDR)-based jammer localization is a promising scheme which locates jammer by successive forwarding of PDR measurements to neighbours in a distributed manner without any modifications to hardware. Since strong jamming signal corrupts the communication of jammed nodes, the PDR value of such nodes drops to zero. As a result, the PDR gradient descent process couldn’t go forward on the jammed nodes, causing a certain location error. In this paper, we put forward a method to enhance the performance of PDR-based jammer localization through dynamic power adaptation. By increasing the transmission power of the consideration node, its communication ability can be reconstructed to exchange message. After message delivering and sharing among jammed nodes, the node with largest Received Jamming Signal Strength (RJSS) value can be found and is taken as the estimation of jammer. Simulation experiments are conducted to evaluate the correctness and effectiveness of the proposed algorithm. Experimental results verify that, the improved localization scheme has a better performance than current PDR-based method.

Title: Pic Based Cell Search against Multi-Cell Interferences in Hetnet Name: Ming Liang Affiliation: Science and Technology on Information Transmission and Dissemination in Communication Networks Laboratory E-mail: [email protected] Abstract The explosive growth of the data traffic demands in cellular network has present more challenges. As the link efficiency is approaching its fundamental limitation, we can only increase the node deploy density to achieve satisfying network capacity. 3GPP focus on Pico-cell overlaid HetNet, in which small cell base stations (pico eNB: pico evolved Node-B) with low transmit power are deployed at the hot spot within a macro cell. However, in today’s already dense deployments, the UE of small cell base station may suffer severe inter-cell interference from the neighboring macro cells. For this, we proposed a par-allel interference cancellation scheme to accomplish the cell search procedure for the low power node in HetNet. PIC scheme can cancel all neighboring cells’ interfering in parallel comparing to the existing SIC scheme. By identifying, reconstruction and cancellation of both the target and interfering signals, we will achieve better cell search performance in HetNet.

Two kinds of features are used separately. The first kind of features is Sift feature which is dealt by SVM classifier. The second kind of features is obtained by calculating each image’s

To mix these two features, we assume two weights for the results probabilities of these two classifiers and exploit logistic regression analysis to build a linear model. Weights is valued by ROC curve. Experimental results show that the proposed approach maintains high recognition rate with a relatively low wrong- recognition rate.

After filtering and computing, it shows the users their contextual information. Context-Awareness can not only extract the context data, but also adjust users’ using environment, e.g. adjusting the background color automatically with the light sensor. In addition, since recommendation systems must face the increasing amounts of data, through the recom-mendation mechanism, we will find out the information need easier. The study stands on three concepts, context aware, location based service, and recommendation system. A mobile App of restaurant recommendation first collects users’ recommend request, users’ context (users’ coordinates, time, weather, speed and directions) and their rating of restaurant. Then, the server, therefore, contain the collection of users’ Place-of-Interest (finding the similar community of Place-of-Interest), rec-ommending items (recommended restaurant) and the contextual classification (recommendation which matches users’ context). As a result, this system can assist users by providing their personalized Place-of-Interest and current context. Also, it finally, enhances the result of the restaurant recommendation. Article ID: 70276 Title: On the Impact of Power Amplifier Efficiency on The Energy Efficiency in A Massive Mimo System Name: Yingchu Guo Affiliation: National Key Laboratory of Science and Technology on Communications, University of Electronic Science and Technology of China E-mail: [email protected] Abstract It is a practical challenge for wireless communication system designs to achieve both high spectral efficiency and energy efficiency because of the nonlinear effect and inefficiency of power amplifier. In previous work, the power amplifier efficiency is always considered as a constant, but it changes with the output power in reality. In this paper, we talk about the impact of variable power amplifier efficiency, propose an energy efficiency model


considering power amplifier efficiency as a variable, and investigate a power allocation scheme based on zero-forcing precoding so that we can guarantee the spectral efficiency and energy efficiency at the same time. Simulation result shows the trade-off between energy efficiency and spectral efficiency, and implies that relatively higher transmit power will be more ener-gy efficient. Article ID: 70278 Title: A New Multi-objective Routing Protocol of Ad Hoc based on Routing Constrains Name: Xueming Wang Affiliation: Guizhou University E-mail: [email protected] Abstract For the most existing MAODV protocol is only improved by a single performance, there is a problem that the comprehensive performance of the protocol cannot be improved as well. By uses of the routing selection mechanism with the constraints of bandwidth, delay and packet loss rate of the original protocol, a new multi-objective routing protocol RCQ-MAODV of mobile ad hoc network is put forward. Simulations are conducted to MAODV protocol and RCQ-MAODV by NS2, the simulation results show that RCQ-MAODV routing performance has greatly improved than MAODV, its transmission rate, delivery rate is increased and the network cost is greatly reduced. This shows that the RCQ-MAODV protocol can provide more comprehensive quality assurance for mobile ad hoc networks. Article ID: 70282 Title: Traffic Information Distribution Model based on Crowdsourcing UGC and User Trust Degree Name: Chenbo Deng Affiliation: School of Electronic Engineering, Beijing University of Posts and Telecommunications, Beijing, China E-mail: [email protected] Abstract

In this paper, we at first analyzed the real-time traffic information and crowdsourcing UGC (User Generated Content) mechanism in today’s in-vehicle network. We then proposed an effective traffic information distribution model based on the crowdsourcing UGC and its production-user trust degree. The model combines the crowdsourcing UGC quality-control strategy, the Shapley power index and the principle of the proportion dynamic balance distribution to output the relatively reliable and real-time traffic information. Next, some of the conceptions have been introduced respectively in detail for the better understanding of this model. Finally, the performance analysis is provided to evaluating the proposed scheme and the simulation results showed that the proposed model have a good performance in the pervasive computing environments. Article ID: 70283 Title: Fft-Based Parallel Encoding Algorithm for Structured Ldpc Codes Name: Yanan Fan Affiliation: University of Chinese Academy of Sciences, Beijing, China E-mail: [email protected] Abstract Structured LDPC, such as RA, IRA, ARA, QC-LDPC etc., are some important LDPC codes, these codes usually have very good performance and facilitate the implementation of encoding and decoding for the structural features they have. A new method for the encoding of the structured LDPC codes has been presented, namely FFT-based parallel encoding algorithm, which uses FFT to realize the parallel encoding of LDPC codes by achieving the circular convolution in the frequency domain. The study shows that the proposed algorithm has lower computational complexity than the previously proposed encoding algorithm. Although transforming to the frequency domain requires complex operations in real domain which increasing the number of the quantization points, the throughput of the encoder has greatly improved because of the increase of the degree of parallelism. The simulation results show that the computational complexity of the FFT-based encoding algorithm has an approximately


linear relationship with the size of sub-circulate matrix, and when this size goes larger, the newly proposed algorithm will possess a lower computational complexity and a higher throughput compared with the previously proposed algorithms.

Article ID: 70285 Title: Virtual Network Mapping Algorithm Based on Load Balancing Multi-objective Particle Swarm Optimization Name: Jun Zhao Affiliation: Wuhan Digital Engineering Institute E-mail: [email protected] Abstract Existing virtual network mapping algorithm does not

consider resource consumption of intermediate node on communication path usually. Minimum resource consumption or shortest path of physical network is regarded as objective, thereby leading to bottleneck due to insufficient resource of intermediate node on communication path, and affecting performance of the whole physical network and subsequent success rate of virtual network. A virtual network mapping algorithm based on load balancing multi-objective particle swarm optimization is proposed in the paper aiming at the problem. Resource consumption of intermediate node is sufficiently considered in the algorithm, double balance of node load and link load is regarded as objective. Meanwhile, the optimal path of particle swarm optimization algorithm is adopted. Experiments show that the algorithm proposed in the paper not only can realize double balance of node load and link load, but also can effectively improve request receiving success rate, overall resource load balance and long-term operation income.

Article ID: 70290 Title: Electromagnetic Wave Propagation Characteristics of Rotating Antenna in Electrical Machine Name: Sonia Ben Brahim Affiliation: Sup'Com E-mail: [email protected] Abstract Nowadays wireless communication for rotating electrical machines is interesting for both real time monitoring and diagnosis purposes. However, the application of this technology can lead to some problems. In fact, in our paper, the experimental results of radio monitoring system are illustrated to prove that one of the major problems of these type of application is the big received power variation range and fast fading wireless channel compared with stationary transmitter. Thus, our work aims to analyze the ElectroMagnetic Wave Propagation (EMWP) characteristics in rotating environments in order to provide a strong theoretical support for developing high-performance radio monitoring system. In particular, the Doppler frequency shift and the electromagnetic wave polarization characteristics in rotating movement will be analyzed.

Article ID: 70298 Title: Middleware for Flexible resource allocation validation Name: Yanhong Yang Affiliation: Beijing Institute of Graphic Communication E-mail: [email protected] Abstract The heterogeneity of the available protocols and hardware platforms makes validation in resource allocation a time consuming and complex work. It needs to involve the hardware platforms, link layer and network layer to verify algorithms. To minimize the unnecessary and repetitive implementation of similar functionalities for different platforms, we present our resource allocation validation (RAV) middleware which supports the discovery of sensor networks and provides flexible resource allocation. RAV enables user to specify XML-based deployment descriptor which can easily modify from link layer to network layer and customize configuration of sensors. In demonstration, three different resource allocation algorithms are tested to deploy network, to dynamically reconfigure and to monitor the changes. Article ID: 70299 Title: Transmit Pattern Synthesis for Mimo Radar Name: Zhongrui, Huang Affiliation: Electronic Engineering Institute, Hefei, Anhui E-mail: [email protected] Abstract This correspondence provides a new method for the op-timal design of transmit pattern synthesis of MIMO radar using independent mainlobe and sidelobe constraints. Given fixed pattern mainlobe errors, we apply quadratic inequality constraint to sidelobe level. In order to enable the resulting covariance matrix to fulfill the practical uni-form elemental power constraint, a basis set is constructed which converts the solution of the covariance matrix into the optimization of the coefficients of the basis matrices set. It can not only reduce the computing complexity of the original optimal model, but also can be


solved effec-tively by the convex optimization. In addition, the scale factor of the desired beam is set as the unite variable so as to reduce the matching error of the MIMO

radar pattern further. Simulations are presented to illustrate the superior performance of the transmit pattern via the proposed method.
