DS/CDMA系统中的一种自适应单用户接收机

A Novel Adaptive Single-User Receiver for DS/CDMA Systems

本文提出了一种在异步多径DS/CDMA系统中基于独立分量分析算法的单用户接收机,这种接收机仅需要已知期望用户的定时和特征波形,计算量小、结构简单.它不但能用于在基站进行多用户信号的上行接收,而且适合于用在移动台进行下行接收.其性能较之匹配滤波器和盲MMSE多用户检测器有很大提高.

A novel single-user receiver based on ICA in asynchronous multipath DS/CDMA channels is proposed in the paper, which require prior knowledge of only the spreading waveform and the timing of the desired user's signal. It is seen that the proposed single-user receiver offer substantial performance gains over the matched filter and blind MMSE multiuser detector.
