摘要

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.

Abstract

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.
