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。
This article briefly describes the working principle of SAWTDL (SAWT tapped delay line), and introduces a case where a semi-coherent spread-spectrum communication system uses SAWTDL as a matched filter for despreading. This paper focuses on several factors that affect the processing gain of the SAWTDL matched filter and measures to overcome these effects in the implementation of the work.
