扩频通信。第一本书
扩频通信.第一本有关扩频系统的专著是R.C.Dixon于1976年出版，是一本IEEE专利，1977年出版。1978年在日本京都召开国际无线通信咨询委员会公布研究成果。1982年在美国召开第一次军事通信会议，两次报告在军事中的应用。1985年美国提出CDMA(码分多址)的概念同年美国联邦通信委员会(FCC)制定扩频通信的标准和规范，逐步转入民用的商业化研究-Spread Spectrum Communication. The first book on spread-spectrum systems is RCDixon monograph published in 1976, is an IEEE patent, published in 1977. In 1978 in Kyoto, Japan, an international wireless communications Advisory Committee published research results. 1982 in the United States held its first military communications conference, two reports in the military applications. The United States in 1985 proposed CDMA (Code Division Multiple Access) the concept of the same year the United States Federal Communications Commission (FCC) the development of spread spectrum communication standards and norms, and gradually transferred to the commercialization of civilian research
