Abstract：There is a positive Lyapunov exponent for a four-dimensional system,which indicates that the system is chaotic.The analogous circuit of this system is realized based on Multism software.The chaotic synchronization of the system is completed by the method of driving-response. The two kinds of schemes are presented.The numerical simulation shows that chaotic signal mixed with the pixel point operation is better than that of synchronous transmission with digital image.
