摘 要:扩展频谱通信是军事保密通信的基本方式,它是采用信息的频谱展宽进行传输的,从而达到抗干扰和信息保密的目的。而目前采用的PN序列具有周期性,为了寻找一种具有真正的随机性扩频码,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,文中介绍了自编码扩频原理,分析了系统的性能,并且进行了仿真。Spread spectrum communications is the basic technique for military secure communication, which spreads the spectrum of information for transmission to achieve anti-jam and information security goal. However, the code being adopted at present is periodicah In order to find one kind of code which is really random, and a spread spectrum technology which is strong capability of anti-jam and security, the conception of self-coded spread spectrum is proposed. This. paper describes the principle of self-encoded system, and analyzes its performance, including the simulation results of the system.
