Abstract

A number of methods have been proposed for synchronizing chaotic systems. In this paper, chaos synchronization in coupled discrete-time dynamical systems is studied an used for data transmission. Especially, practical impulsive synchronization scheme for discrete time chaotic system is proposed. Simulation results finally demonstrate the effectiveness of the method. Experimental results show that chaotic system can be synchronized by impulses sampled from state variables. The impulsive synchronization can be applied to almost all chaotic and hyperchaotic systems even in the case when continuous synchronization schemes fail to work.
