智能天线中一般的MMSE接收机缺乏有效跟踪Rayleigh衰落信道变化的机制。在分析了MMSE接收机在Rayleigh信道中的特点之后 ,提出一种新型的CDMA系统MMSE接收机。计算机仿真结果表明 ,此接收机性能较好 ,适用于Rayleigh衰落信道。
A typical MMSE receiver in a smart antenna lacks a mechanism to effectively track Rayleigh fading channel changes. After analyzing the characteristics of MMSE receiver in Rayleigh channel, a new type of CDMA system MMSE receiver is proposed. Computer simulation results show that this receiver performs well and is suitable for Rayleigh fading channel.
