Ultra-Width Band Wireless Communication With Time Pulse Position Modulation

Ultra-width band(UWB) is an new wireless communication technology in time domain, More comprehensive attention has been taken to it because of its low power consumption, good ability of anti-interference and anti-multiple-path and high system capability. In this paper, hot topic about if is summarized, the basic principle and the key technologys of ultra-width band(UWB) with time pulses position modulation such as multiple access, impulse signal, modulation, transmission and receiving, cross-relation ect, are discussed as well as its applications, especially the analysis and comparing of modulation technologies are given in detail. The results show that UWB radio is very potential in coming wireless communication.
