扩频通信系统中的SAWTDL匹配滤波器

SAWTDL Matched Filter for Spread Spectrum Communication Systems

本文简要叙述了ＳＡＷＴＤＬ（声表面波抽头延迟线）的工作原理，介绍了一个半相干扩频通信系统用ＳＡＷＴＤＬ作匹配滤波器进行相关解扩的情况。着重探讨影响ＳＡＷＴＤＬ匹配滤波器处理增益的几种因素和工作实现中克服这些影响的措施。

Abstract ：This paper describes briefly the principle of a SAWTDL matched filter and co- herent spread spectrum demodulation in a half coherent spread spectrum communication sys- tem using it． In the paper several factors which affect on processing gain of SAWTDLmatched filter are discussed emphatically and some measures that overcome them are given.
