Thus the technology has the performance characteristics and enormous development potential the traditional technologies would not have. However, it is still difficult to fully realize this technology. This paper mainly discusses the AWGN channel, derives system and communication environment under the condition of non-best receiver, cross-correlation relationship between the template pulses, lays a theoretical basis for design and implementation of ultra-wideband communication test system. 【Key words】the wireless pulse communication；error bit rate；cross-correlation template pulse 0 引言 解决的问题。 随着互联网的迅速发展和人们对信息需求的日益提
