摘要

本文讨论的接收机是用于DS/CDMA系统的多级自适应阵列和串行干扰消除联合接收机(AA-SIC)

介绍的接收机同时使用了空域和时域处理以及多用户联合检测技术.一般的联合接收机要使用RAKE单元

本文所讨论的接收机没有使用RAKE单元

而利用智能天线的自适应算法能起到分集接收的功能

不仅能抑制多址干扰信号

而且构成简便

计算时间较短

有利于实际应用.

Abstract

A new multistage joint adaptive array and successive interference cancellation (AA-SIC) structure for a direct sequence code division multiple access (DS/CDMA) system are proposed.In the structure of the system

space

time processing and multiuser detection to improve the performance are utilized.Most structure needs RAKE combiner to capture the multipath

but the proposed structure needs no RAKE combiner and its adaptive algorithm has the function of RAKE combiner.
