摘要
介绍了基于区间同步恢复记忆实现混沌保密通信的方法 .在发射端发射调制信号的同时发送一个伴随的二进制序列 ;在接收端利用混沌系统的约束同步和自由演化同步使接收混沌系统和发射混沌系统达到同步 ,同时利用接收到的二进制序列完整地将所传送的语音信号提取出来 .最后以修正Logistic映射对语音信号进行计算机仿真 ,结果表明 。
The realization of chaos secure communication based on the method of interval synchronization recalling memory is provided. It sends a binary sequence when sending modulated signal by the transmitter. By forced synchronization and freely evolving synchronization, synchronization is maintained between transmitter and receiver system. At the same time, by the receiving binary sequence the speech signal can be recovered wholly and exactly. Finally, computer simulation of modified Logistic chaotic system is given, and the results prove that the method is valid.
