Abstract	The impulse ultra-wideband (UWB) channels covering the frequency range from 2 to 10 GHz, it covers indoor residential, door office, outdoor, industrial, and open outdoor environments. UWB communications systems share the spectrum with other systems in an unlicensed manner. This has caused a strict spectral constraint. In order to discuss power spectrum distribution, it analyzed the channel modeling subgroup of IEEE 802.15.4a from three aspects: the average pathloss, the power delay profile and the small-scale fading statistics. Theoretical analysis and simulation of the 2-10GHz power spectrum distribution of UWB system is described in detail. The power spectrum influence of 8 channels upon DS-PAM UWB system is analyzed. Simulation results show that the performance of UWB system isn't deteriorated by multi-path channel, and impulse UWB has better performance in anti-multipath interference.
