摘要
深入地研究了WCDMA下行链路的几种接收机,阐述了下行链路的接收原理。分别对相应的算法进行了详细的分析,并比较它们的优缺点。文中给出了RAKE接收算法,LMMSE-RAKE接收算法和自适应LMMSE接收算法的实现方案,针对典型的WCDMA系统环境进行仿真,比较相互之间的性能。这对于实际设计下行链路接收机具有重要的指导意义。
This article investigates several downlink receivers in WCDMA mobile communication system. It explains the principle of downlink receiver and analyzes different algorithms. Based on the simulation result, it compares the performances of RAKE receiver, LMMSE - RAKE receiver and adaptive LMMSE receiver, which is very useful for the practical design of downlink receiver.
