摘要

本文首先在码片匹配滤波的基础上为多径CDMA信道环境的接收机提出四种数据选择方案

分析了各种数据方案对多址干扰与码间干扰的影响;接着提出了基于Rosen梯度投影实现的最小均方盲空时多用户检测方法并分析了四种数据选择方案对其运算复杂度的影响;最后通过仿真实验结果的分析比较给出较合理的实现方法

该方法在降低运算量具有一定的优势

因而更加具有实用意义.

Abstract

In this paper

We first present four data-selected schemes based on chip-matched filter for the multiuser receiver in multipath CDMA channels

and study the impact of these schemes on multiple-access interference (MAI) and inter-symbol interference (ISI).Then

we present the least mean-square (LMS) blind space-time multiuser detection method based on the Rosen's gradient projection

and analyze the effect of these schemes on the computational complexity of the presented detection method.Finally

we provide a reasonable and realizable method by analyzing the results of the simulations

and this method has the advantages of lowering the computational complexity

therefore it is interesting for application.
