基于間歇耦合和廣義混沌同步的數(shù)字信號傳輸方案

Digital communication based on occasional coupling and generalized chaotic synchronization

  • 摘要: 該文討論了一種基于間歇耦合思想和廣義混沌同步的保密通信方案。在這種數(shù)字信號傳輸過程中,每個信號周期被分為兩部分T1,T2,分別用于實(shí)現(xiàn)同步和信號提取,分析了T1,T2與安全性能和信息解調(diào)精度的關(guān)系。數(shù)值仿真表明效果良好。
    Abstract: In this paper, a way of secure digital communication based on occasional coupling and generalized chaotic synchronization is proposed. The period of every signal bit is divided into two parts: T1 and T2. During T1, generalized chaotic synchronization is fulfilled, and in T2, the transmitted signal is extracted by a special way. The relation between T1, T2 and the security as well as the performance of signal extraction are also analyzed. Numerical simulations are performed to show the effectiveness of this communication scheme.
