Summary I: Alamouti or SMX v.s. CSMX (Sub_BC)• Sub_BC outperforms Alamouti (Rate=1) in PER• Sub_BC without one OFDM symbol decoding (STBC) delay• The transmit diversity gain (up to 8dB at 10% PER or more at 1%
PER in channel B) from CSMX over SMX will– reduce the required high EVM at TX– reduce the required high SNR at RX
• Sub_BC can be implemented to 2xN Alamouti (Rate=1)– For example: 2xN ALA v.s. 2(M)xN CALA in 04/934r2.
• Rate 4(M)xN, M>4 can be implemented to relax the required SNR to support high data rates with four spatial streams if necessary.

Summary II: Sub_BC v.s. Beamforming (BF)
• Do not require feedback of CSI from RX to TX• Do not require that the channel is reciprocal • All MAC/PHY feedback modes required for BF in
IEEE-04/889r0 can be eliminated. • Simpler MAC without feedback modes greatly improves
the MAC efficiency (i.e., throughput) and complexity.

Thank you!!
The dream of 11n greedy data rates comes at extreme cost of required SNR (EVM) if challenged in the real MIMO channels. The proposed circulation transmission explores optimal antenna diversities without feedback, relax the required SNR, and make the speedy dream come true.
