Abstract :
In the paper, pulse design methods for Ultra-wideband (UWB) system are presented. One method is a modified method based on prolate spheroidal wave function; the other is an improved wavelet-based pulse design, which changes the searching method from two dimensional random variables to one dimensional random variable. Simulation results show that both methods can generate pulse shapes which comply with FCC regulation. Meanwhile the latter method has higher spectral utilization ratio than the former.
