Simulation and Analysis of Ultra-Wideband Signals Power Spectrum

UWB signals and their power spectrum mask are important factors which need to be considered when studying the spectrum coexisting and compatible problems between UWB systems and other radio systems.In this paper,according to the characteristics of UWB signals,the influence of Gaussian pulse and its derivatives,different information modulation mechanisms and time-hopping parameters on the power spectrum mask of UWB signals is simulated and analyzed from the view of power restriction,and the methods for controlling the power spectrum mask are concluded.This study will provide some useful ideas and methods for settling spectrum coexistence problems between UWB communication systems and other radio systems.
