扩频通信新方向——自编码扩频

The New Domain of Spread Spectrum Communication——Self-Coded Spread Spectrum

扩频通信是把信息的频谱展宽进行传输的技术 ,而目前我们采用的PN序列具有周期性 ,为了寻找一种扩频码具有真正的随机性 ,并具有较强的抗干扰和信息保密能力的扩频通信技术 ,人们提出了自编码扩频的概念 。

Spread spectrum communications is the technology of spread the spectrum of information for transmission, however, the code that we are using presently is periodical. In order to find one kind of code which is really random, in addition, this spread spectrum technology have a strong capability of anti-interaction and secrecy, some people have expounded the conception of self-coded spreadspectrum, its principle reciprocal crucial technology are discussed in this article.
