Abstract :
Ultra-wideband wireless communication system transmits impulse signal, and the spectral character of UWB signal can provide important insights into design and interference performance of UWB communication system. In this paper, based on modulation methods of the Time-Hopping UWB and the Direct-Sequence UWB, two mathematical models of the random impulse signals are given, and Power Spectral Density (PSD) expression are carried out using stochastic theories, respectively. Furthermore, the related simulation and spectral analysis is provided to find the main effect factors of the PSD distribution.
