说明：  扩展频谱技术有多种基本实现方式，本文主要介绍的是直接序列 扩频技术，特别针对二进制的PSK 调制解调技术，直接序列扩频系统的抗干 扰能力分析与直接序列扩频系统的同步方法，并进行了相关仿真分析
(Spread spectrum technology has a wide range of basic ways, the introduction of this paper is a direct sequence spread spectrum technology, particularly for binary PSK modulation and demodulation techniques, direct sequence spread spectrum system, anti-jamming capability analysis and direct sequence spread spectrum system synchronization method and simulation analysis of the relevant)
