Radio Propagation for Wireless Ultra-wide Band Systems

Wireless ultra-wide band(UWB) wave has been studied by incomplete Mathematical Method, the multiple paths of electromagnetworksic wave on UWB broadband is described from propagate to receive, and analysis mechanism of quality that is affected on the channel by received signal quality: propagation, Teflection, and Transmisson,: practice shows that the Mathematical method can explain the channel characteristics are influenced by the buildings, vegetation and terrain, Review on the crucial effect from the quantum theory on the characteristic and mechanisms of UWB signal, so there are the guidable function which mathematic models are been setted up for the channel indoor and outdoor models .
