Synchronization Of Chaotic Systems And Its Applications In Communications,

The paper studies the chaotic characters and analyzes the ways of designing synchronization, basing on the theory of nonlinear control and stability analyse. Then we apply synchronized systems to transmitting information.In the part of synchronization design, we analyze the way to improve PC's performance, considering internal and external noise's effect. We apply linear and nonlinear feedback in design, which enhances synchronization's agility and validity. The paper points out that chaotic synchronization can be seen as the problem of nonlinear observer design and stability analyse. We study the synchronizing approach of generic chaotic systems. This paper emphasizes on one typical system-Lur's synchronization and utilizes the LMI to improve its robust performance.There are two ways applying the synchronized systems in communication: chaos masking and chaos mapping. The paper mainly studies the latter. We make use of the super-chaos configuration and parameter map in the digital information transmitting, which are proved to be with high security by simulation.
