In UWB we have to control the output power perfectly
in order to avoid the interference with other systems
The channel effects play an important factor in UWB
signal detection, due to power limitation and severmultipath effects.
We have to consider any obstacle or channel effects,
distinguish between narrow and broad environments
and line of Sight and Non Line of Sight propagation.
Its an important to know the profile of the channel
and statistical model of paths arrival time to be used in
Rake receiver.U l t r a W i d e b a n d C h a n n e l M o d e l a n d S i m u l a t i o n 3/22

1) Indoor residential
2) Indoor office
3) Industrial environments: arecharacterized by larger enclosures (factory halls),
filled with a large number of metallic reflectors. This is anticipated to lead to severe
multipath.4) Body-area network (BAN): communication between devices located on the body,
e.g., for medical sensor communications, "wearable" cellphones, etc. Due to the fact
that the main scatterers is in the near field of the antenna, and the generally short
distances, the channel model can be anticipated to be quite different from the other
environments.
5) Outdoor: suburban-like microcell scenario, with a rather small range.6) Agricultural areas/farms: for those areas, few propagation obstacles (silos,
animal pens), with large dististances in between are present. Delay spread can thus
be anticipated to be smaller than in other environments

Power Delay CharacteristicsAccording to a very short pulse therefore
multipath components arrive in Poisson
distributed clusters. Furthermore, within
each cluster, the path arrivals are alsodescribed
by a Poisson process. Both cluster interarrival
times and path interarrival times, are thus
exponentially distributed with model
parameters that are experimentallydetermined
