对变量反馈微扰混沌同步方法进行了改进，在发送端，将系统的部分信号进行小波变换去掉细节信息后发送，在接收端重构出低频信号，然后将其与接收端信号的差进行离散反馈，可以使两个结构相同的混沌系统达到同步，并讨论了反馈因子、噪声、参数失配对混沌同步的影响。应用本同步方法可将发送信号压缩后传送，节约系统资源；滤去发送信号中的高频成分，减小干扰对同步信号的影响。文中给出了仿真验证结果
The method of variable feedback perturbation and chaos synchronization is improved. At the transmitting end, some signals of the system are transformed by wavelet to remove the detail information and then transmitted. The low-frequency signal is reconstructed at the receiving end, and then the difference between the received signal and the signal at the receiving end is discretized Feedback, two chaotic systems with the same structure can be synchronized and the influence of feedback factor, noise and parameter mismatch on chaos synchronization is discussed. Applying the synchronization method, the transmitted signal can be compressed and transmitted to save system resources; the high frequency component in the transmitted signal is filtered to reduce the influence of interference on the synchronous signal. The paper gives the simulation results
