摘要

在WCDMA通信系统中，Rake接收机由于具有抗多径衰落的特性，被用于传输数据的检测。但耙式接收机将多用户干扰(MUI)视为AWGN，在高信噪比条件下克服多址干扰(MAI)的影响存在局限性。本文采用了去相关匹配滤波器，消除了干扰，提高了系统性能。仿真结果表明，与RAKE接收机相比，去相关RAKE接收机在误码率方面的性能有了显著提高。分析了不同扩频系数下去相关接收机的性能。

Interference suppression using de-correlating rake receiver in case of WCDMA

Rake receivers are used for the detection of transmitted data in case of WCDMA communication systems due to its resistance to multipath fading. But rake receiver treat multiuser interference (MUI) as AWGN and have limitation in overcoming the effect of multiple access interference (MAI) when the SNR is high. A de-correlating matched filter has been used in this paper, which eliminates and improves system performance. Simulated results show a significant performance improvement for De-correlating RAKE receiver in terms of BER compared to a rake receiver. The performance of the de-correlating receiver for different spreading factor is also analysed.
