【摘要】 混沌信号具有类随机的性质,这就使得混沌信号越来越广泛的应用于保密通信系统中。介绍了通过采用LM I(L inearM atrix Inequation)设计反馈系数的方法,实现同步通信信息的保密性,并通过MATLAB仿真证明了结论的正确性。在信号传输过程中,当混沌系统达到同步以后,在其接收端能恢复出原始信息,从而实现混沌系统的保密通信。更多还原

【Abstract】 The chaotic signals have the quality of genus-randomness,so that the application of chaotic signals is more and more widely used in the secure communication.This paper presents LMI(Linear Matrix Inequation) to design the feedback coefficient,the security of synchronization communications is realized,and MATLAB simulation indicates the validity of the conclusion.On the condition of synchronization,the receiver can recovers the information,so that the secure communications of chaotic system is realized.更多还原
