混沌保密通信的研究

Secure Communication via Synchronized Chaotic Circuit

采用自行设计的由ＯＴＡ和Ｏｐａｍｐ实现的压—流混合型保密通信电路，从计算机仿真和实验两个方面进行了模拟信号的振幅隐蔽调制—解调、扩频调制—解调以及数字信号参数调制—解调的研究．

In this paper, voltage current hybrid secure communication circuit is proposed based on the variable parameter of current type synchronized chaotic circuit which offered by author earlier.The study of signal amplitude masking modulation, spread frequency modulation and parameter modulation of digital signal are discussed in both computer simulation and experiments.
