基于单信号实现多组混沌系统同步的仿真研究

Simulation of Multi-set Chaotic Systems Synchronization by Transmitting Scalar Signal

为了提高保密性和实用性,混沌系统同步方法所追求的目标是:利用主动系统较少的信号实现两个或者多个混沌系统的同步。提出了利用一条传输线进行多个信号的传输的方法,并将其应用实现混沌系统的同步。其信号传输方法基本思想是:多个信号在传输的过程中交替使用采样和保持这两种方式,多个信号在一条传输线中进行传送。探讨了利用所提出的多信号传输方法用于解决多组混沌系统的同步问题。仿真结果验证了该方法的有效性和可行性。

In order to improve secrecy and practicability, the aim is the small number signals from the master chaotic system used for chaos synchronization. A new method of multi-dimensional signal transmission via one single transmission channel for chaos synchronization was proposed and it was applied to realize chaos synchronization. The basic idea is to use both the sampling and holding modes alternately during the transmission process so that multi-dimensional signals can be transmitted by sharing the single transmission channel. The proposed method was then applied to solving multi-set chaotic systems synchronization problems. Simulation results show the effectiveness of the method presented.
