摘要
文中研究了混沌系统的广义同步和基于状态观测器同步。利用这两种同步方法,研究了统一混沌系统同步。研究发现:同步后的响应系统能保持混沌状态。在基于状态观测器同步的基础上,提出了全双工保密混沌通信系统,理论分析和仿真实验证明了该通信方案的可行性。
This paper studies the generalized synchronization and synchronization based on state observer of chaos. By utilizing these two synchronization methods,the synchronization of unified chaotic system is studied. The study reveals that the responsed system remains in chaos after the system is synchronization. On the basis of synchronization based on state observer,the full duplex of secure communication is proposed. The theoretical analysis and simulation proves that the communication schcme is practicable.
