CHAOTIC COMMUNICATION SYSTEM BASED ON SLOPE MODULATION
-
摘要: 本文将提出一种利用混沌信号进行通信的新方法,这种方法是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,在接收端再用相反的方法将原始信号解调出来。本文将给出电路的基本形式和电路仿真结果。

Abstract: In this paper, a new method of communications using chaotic signal is presented. This method is that the slope of the non-linear resistance in Chua s circuit is modulated with the input signal. At the receiving end, the signal is demodulated using the inverse course. Finally, the basic circuit and simulation result are given. -
