为了验证混沌在通信系统中的同步，做了蔡氏混沌同步原理的仿真实验。建立两种基于蔡氏混沌的保密通信系统，通过系统仿真得出基于环形蔡氏混沌的通信系统要优于基于传统蔡氏混沌通信系统。提出两种在混沌通信系统中加入信号的方式，仿真分析不同的信号加入方式对于混沌系统性能的影响，得到用加法器在混沌系统中加入信号可以改善保密通信系统的频率响应特性。

The simulation experiments for Chua chaotic synchronization principle were done to verify the chaotic synchroni-zation in communication systems. Two secure communication systems based on Chua chaos were established. The simulation re-sults show that the communication system based on the ring Chua chaos is better than that based on traditional Chua chaos. Two ways to add the signal in chaotic communication system are presented. The effects of different signal adding ways on chaotic sys-tem performance are analyzed and simulated. The conclusion that the frequency response characteristics of secure communication system can be improved by adding the signal into chaotic communication systems by summator is given in this paper.
