Synchronous performance analysis and application based on CNN hyperchaotic system

Constructing the state observer can achieve chaotic synchronization. Conventional research method is to achieve synchronization through installing pole arbitrarily, but seldom do analysis on the performance of synchronous system. The paper design a novel five-dimensional CNN hyperchaos synchronous system, analysis shows that pole configuration and synchronous speed have intimate relations. In order to maximum decrease the synchronous error disturbance which is created by noise between the transmitting and the receiving system, we propose the way of selecting the feedback matrix and making up for differences. This scheme is applied in image disorder system, the emulation results indicate this design method is feasible and can be applied in multimedia secure communication.
