研究了一种自适应ＤＳ－ＣＤＭＡ信号匹配滤波接收机。在这种接收机中，利用一个自适应匹配滤波器，根据最小均方误差准则，对接收匹配滤波器系数（参考向量）作自适应调整。在白噪声情况下，自适应接收机等效于传统匹配滤波器。当存在干扰和多径时，自适应接收机能够抑制干扰，合并多径，从而实现对发送信号的最佳检测。本文对多址干扰情况下接收机的性能进行了分析，并给出了仿真结果。结果表明，这种接收机的误码性能虽然随着用户数的增加恶化，但通过增加信噪比（Ｅｂ／Ｎ０），可以将误码降到任意低的水平。
An adaptive DS-CDMA signal matching filter receiver is studied. In this receiver, an adaptive matched filter is used to adaptively adjust the received matched filter coefficients (reference vectors) according to the minimum mean square error criterion. In case of white noise, the adaptive receiver is equivalent to the traditional matched filter. When interference and multipath exist, the adaptive receiver can suppress the interference and combine the multipath to achieve the best detection of the transmitted signal. In this paper, the receiver performance under multiple access interference conditions are analyzed and the simulation results are given. The results show that the error performance of this receiver, while deteriorating with increasing number of users, can be reduced to any low level by increasing the signal-to-noise ratio (Eb / N0).
