Spectral Characteristics of Ultra Wideband Multiple-Access Signals

Zheng Ji

Abstract

Ultra wideband(UWB)signaling is an important new emergent technology for wideband multiple access communication system.A theoretical analysis of UWB signals for various modulation methods is presented.Power spectral density for the time hopping modulated UWB and for a direct sequence phase coded UWB approach are detailed,which can provide important insights into the design and interference performance of UWB communication system in a multiple access environment.
