摘要

多址干扰是直扩码分多址系统中的一个主要问题.多用户检测技术和阵列天线已成为解决这一问题的两种主要方法

将这两种方法结合起来的空时处理能大大提高系统的容量和性能.本文提出了一种空时盲自适应RAKE接收机.研究结果表明

该接收机具有较强的抑制多址干扰和克服"远-近"效应的能力

且能快速收敛.

Abstract

Multiple access interference(MAI) is a key problem in DS-CDMA.Both multiuser detection method and array antennas have been introduced to reduce the effect of the MAI respectively.In this paper

the two methods are combined and a novel space-time blind adaptive RAKE receiver is presented.With numerical simulations and performance analysis

it is shown that the receiver has the excellent performance in eliminating the MAI and resisting the effect of the"near-far"problem.Furthermore

the adaptive version of the receiver can converge rapidly.
