摘　　要：本文讨论扩展频谱通信系统中有关相位的捕获与跟踪技术问题。首先在扩频通信系统原理的基础上结合实际系统中的应用条件 ,详细分析了捕获的方法、性能特点 ,给出了比较适用的 2种捕获与跟踪原理图。理论分析与实验结果表明 ,所采用的分析方法和捕获方案是可行的。In this paper acquisition and code tracing technology for spread spectrum communication systems is analysed. At first,a principle of spread spectrum communication systems is introduced. Methods and performances of acquisition are analysed. Two acquisition and code tracing schematic diagrams are given. Both the theoretical analysis and experimental results indicate that the adopted analysis method and the supposed synchronization scheme are feasible.
