Abstract

Abstract: This paper studies the generalized synchronization and synchronization based on state observer.Utilizing two kinds of this method，sychronized control of unified system is studied.The study discovers that the responsed system is chaos after the system is synchronization.On the base of that，the full duplex of secure communication is presented.The theoretical analysis and simulation illustrates that the plan of communication is effectiveness and feasibility.

Key words: unified chaotic system, generalized synchronization, state observer, secure communication

摘要： 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的同步控制。研究发现：同步后的响应系统能保持混沌状态。在此基础上，提出了全双工保密混沌通信系统，理论分析和仿真实验表明了该通信方案的可行性和有效性。
