本论文围绕伪随机码的捕获展开，主要研究了直接扩频通信系统的性能特点、

伪随机码的产生与相关性、重点是伪随机码的捕获，提出了一种新型的捕获方法

——双向滑动捕获法，并针对双向滑动捕获法进行了一些理论分析和探讨。-In this paper, around the pseudo-random code capture started, mainly to study the direct spread spectrum communication system performance characteristics, pseudo-random code generation and correlation, with a focus on the capture of pseudo-random code, a new type of capture method- two-way Sliding capture and recapture method for two-way slide for a number of theoretical analysis and discussion.
