1 无线扩频通信技术简介扩展频谱通信(Spread Spectrum Communication)的研究始于二次世界大战末,鉴于技术复杂,价格昂贵、相关学科综合要求很高等原因,直到80年代末期,才逐渐进入实用阶段。随着无线通信的广泛应用,无线频道变得非常拥挤,频道资源非常紧张,干扰繁多。由于扩频通信技术有很多优点可以克服这些问题,并且可以提供更高的保密技术,因此,从80年 A Brief Introduction to Wireless Spread Spectrum Communication Spread Spectrum Communication began its research at the end of World War II. Due to the complexity of technology, the high cost and the high comprehensive requirements of related disciplines, it was not until the late 1980s that it gradually entered the practical stage . With the widespread use of wireless communications, wireless channels become very crowded, channel resources are very tense and interfere with many. As spread spectrum communication technology has many advantages to overcome these problems and can provide higher security technology, so from 80 years
