摘要
超宽带(UWB) 无线通信技术是一种利用时域资源的通信新技术,因其具有低功耗、良好的抗干扰和抗多径的能力和高的系统容量而受到普遍关注。本文对超宽带的历史和超宽带的基本原理及其关键的技术作了简要的介绍。并对UWB通信中的接收做了进一步的分析,对未采用分集接收以及采用分集接收的接收机误码率作了理论分析,并利用MATLAB进行了仿真,分析与仿真结果表明,在超宽带无线通信系统中引入分集技术,系统的误码率有了较明显的改善。

Abstract
Ultra-wideband (UWB) is a 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 multiple path and high system capability. The paper simply introduced the history of UWB, the basic principle and the key technologies of UWB. Especially, We had a further analysis about the receiving in the UWB communication system. Then we analyze the bit error probability performance of the two models that using diversity technology by MTLAB .The results obtained are compared by theoretic analysis and computer simulation .The simulation results show that it has apparently improvement of the bit error probability after lead diversity receiver into the Ultra-width band communication system.
Keywords: Ultra-width band;Time Hopping ; Pulse Position Modulation;Correlation-receive; Diversity Receive
