基于区间同步实现混沌保密通信

Realization of the Chaotic Secure Communication Based on Interval Synchronization

利用区间同步方案实现混沌保密通信是基于脉冲和语音信号有一些间隙或一些幅度相对弱的区间的特点．在发射端，对语音信号在时域内进行压缩使其出现幅度为０的一些区间，然后将脉冲信号或压缩后的语音信号对混沌信号进行调制．在接收端，利用约束同步和自由演化同步，将所传送的脉冲信号或语音信号从已调制的混沌信号中提取出来．最后。

Interval synchronization is used to realize chaotic secure communication. It assumes that pulse signal or speech signal has some intermittence or intervals during which time the signal amplitude is relative week. In transmitter, compressed speech signal has some zero intervals in time domain. Chaotic signal is then modulated by pulse signal or compressed speech signal. In receiver, pulse signal or compressed speech signal is extracted from modulated signal by forced synchronization and freely evolving synchronization. Finally, computer simulation is given with Henon map and Dufing chaotic systems.
