Algorithm for UWB Pulse Design and its Performance Analysis

Ultra wide band (UWB) is an ideal candidate for achieving high data rates over short distances with low cost and low power consumption. In this paper, we propose a simple pulse design method that uses the iterative combination of five Rayleigh derivatives to meet the FCC UWB indoor spectral mask requirements. The performance comparison between the combination pulse and the second derivative Gaussian pulse is also presented by means of the computer simulation. The simulation results show that the power spectrum density (PSD) of the combination pulse approaches the FCC spectral mask obviously, and the performances of UWB system using combination pulse are better than that using the second derivative Gaussian pulse.
