摘　　要：简要地介绍了蔡氏电路及蔡氏二极管的实现方案并且利用输入信号对蔡氏电路中的非线性电阻的电导值进行调制,在接收端则用相反的方法将原始输入信号解调出来。给出了具体的实现电路和仿真分析的结果。仿真结果表明:这种方法能够正确地解调出加密信号达到保密通信的目的。Approaches to realize Chua＇s circuit and Chua＇s diode are simply introduced and the slope of the non- linear resistence in Chua＇s circuit is modulated with the input signal. At the receiving end,the signal is demodulated using the inverse course. In this paper,the circuit and simulation result are given. The computer simulation illustrates that encrypted signal can be correctly demodulated in the receiver in order to realize secure communication.
