摘要

移动信道的主要特征是由移动和多径传播所产生的多径衰落现象。在高速移动通信系统中，必须采用抗多径衰落技术，才能实现有效传输。本文首先概述了移动信道的数学模型及其典型形式，在此基础上，分别讨论了时分多址（ＴＤＭＡ）和码分多址（ＣＤＭＡ）系统的抗多径衰落方法──自适应信道均衡技术及多径分集接收技术，并简述了近年来较为活跃的多用户检测技术和自适应天线分集技术。

Abstract

The mobile communication channel suffers from severe fading distortion due to multipath phenonmenon. This makes it necessary to adopt anti-multipath techniques in high speed mobile communication systems. On the basis of an overview of typical mobile communication channels

this paper presents survey on anti-multipath techniques in TDMA and CDMA mobile communications systems

with special attention paid to adaptive channel equalization

RAKE receiver and multiuser detection.The recently proposed diversity technique using adaptive array is also addressed.
