摘要
对混沌电路同步进行了理论分析，着重讨论了电路参数对同步建立时间的影响，并提出了缩短同步时间的方法．还讨论了利用混沌实现通信加密的设想，通过ＰＳＰＩＣＥ软件对提出的混沌加密数字通信系统进行了模拟，并在实验室实现了混沌键控调制解调数字通信实验电路，就低速率信号进行了测试。
The synchronization of chaotic circuits is theoriticaly analysed. We have studied the influence of circuit parameters on the synchronization establishment time. A secure digital communications system with chaotic shift keying modulation was proposed. The system was simulated by PSPICE at PC and realized in our laboratories. The results were exposed.
