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 sever multipath 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. It’s an important to know the profile of the channel and statistical model of paths arrival time to be used in Rake receiver.

1) Indoor residential 2) Indoor office 3) Industrial environments: are characterized 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 Ultra WidebandUltra WidebandChannel Model and SimulationChannel Model and Simulation 4/22 Outlines Introduction Overview of the Considered Environment Generic Channel Model Channel parameters Parameterization and channel impulse response References

Power Delay Characteristics According to a very short pulse therefore multipath components arrive in Poisson distributed clusters. Furthermore, within each cluster, the path arrivals are also described by a Poisson process. Both cluster interarrival times and path interarrival times, are thus exponentially distributed with model parameters that are experimentally determined Ultra WidebandUltra WidebandChannel Model and SimulationChannel Model and Simulation 6/22 Reflection Clusters of large shifted pulses Scattering Clusters of overlapping pulses Diffraction Clusters of small shifted pulses Outlines Introduction Overview of the Considered Environment Generic Channel Model Channel parameters Parameterization and channel impulse response References
