摘要/Abstract

摘要： 基于IEEE 802.15.3a建议的超宽带密集多径信道模型，对采用最大比和等增益两种合并方式的RAKE接收机的高速超宽带通信系统的性能进行了研究.理论分析和计算机仿真结果表明，在密集多径环境下，采用复杂度相对较低的等增益合并SRAKE接收机，可以使通信系统达到良好的误码率性能，所以其更适合于超宽带通信系统.

Abstract: The performance of UWB communication system, which employs RAKE receiver with maximum ratio combining and equal gain combining, is researched based on the channel models proposed by IEEE 802.15.3a. BER performances are obtained via theoretical analysis and computer simulation. The results show that in dense multipath environment, SRAKE receiver using equal gain combining with low complexity can achieve good performance, so it's fit for UWB communication system.
