| 摘 要： | 分析了Liu混沌系统的特性,讨论了一种观测器同步设计方法.首先对响应系统状态进行重构,然后通过极点配置方法,实现两个混沌系统的状态渐进同步,并通过数值仿真对理论分析加以验证.提出利用Liu混沌系统同步进行图像保密通信的方法,在发送端利用Liu混沌信号掩盖坐标变换后的数字图像信号,在接收端能准确地恢复原始图像信号.仿真结果表明了提出的图像保密通信方法具有很好的保密性.

| Abstract: | The characteristics of Liu chaotic system were analyzed,and an observer synchronization design method was discussed.First,state of driver system was reconstructed.Then the states of two chaotic systems were asymptotically synchronized by pole assignment.Numerical simulation was carried out to verify the theoretical analysis.A method for image secure communication was proposed by using this synchronization chaotic system.At sending terminal,digital image signals after coordinate transformation were masked by... |
