摘　　要：基于Jonathan N Blakely等人提出的新型高速Lorenz电路,提出了混沌调制保密通信电路的模型,并采用PSpice软件对保密通信电路的特性进行了仿真研究.研究结果说明了混沌调制保密通信方案的正确性,并给出了接收端和发送端电路参数不一致对通信的影响,调制信号幅度和频率对原有混沌电路的影响,以及噪声对传输质量的影响等.A chaotic modulation secure communication scheme based on a new type of high-frequency Lorenz-circuit is proposed. Some features of the chaotic modulation circuit are investigated with the software PSpice. The results proved the Validity of the scheme, the influence of the difference between transmitter and receiver the amplitude and frequency range of original signal, and the noise to the communication are also presented.
