摘要
文章详细地介绍了统一混沌系统和Pecora-Carroll同步法,用P-C法实现统一混沌系统同步,提出了一种新颖的保密通信系统,并用Matlab6.5/Simulink仿真软件进行建模仿真。结果表明,该系统能够正确地解调出原始加密信号,达到保密通信的目的。
In this paper, an unified chaotic system and synchronization method of Pecora-Carroll＇s are discussed in detail. For the synchronization of the unified system by P-C＇s method, a novel secure communication system is presented in brief including its model and simulation by softwre of Matlab6.5/Simulink. The simulation illustrates that encrypted signal can be correctly demodulated in the receiver, and the secure commnication is thus realized.
