滤波信号驱动的混沌同步方法

Chaos synchronization with filtered signal driving

为了提高混沌信号在异地信息处理中的同步性能,研究了受滤波而产生的畸变信号驱动的混沌系统同步方法.该方法假设驱动接收系统的信号是由混沌发射信号通过滤波器产生,首先通过滤波信号的变换获取同步信号,然后采用驱动-响应同步或耦合同步技术实现混沌系统的同步.基于驱动-响应同步技术,阐述了使用滤波信号实现混沌系统同步理论;以Lorenz系统为例,研究了低通滤波驱动系统同步的性能.理论分析和模拟结果表明,所提出的方法是稳定的,可节省信号的传输带宽.

To improve the synchronization performance of chaotic signal in remote information system,the chaos synchronization method with the filtered signal driving was studied.Assuming that the driving signal is produced by filtering the chaotic signal generated from the transmit system,this method first makes some type of transformation with the filtered signal to obtain the synchronizing signal,and then realizes chaotic systems synchronization using the drive-response synchronization or the coupling synchronizati...
