A synchronizing method for hyper-chaotic systems

A synchronizing method for hyper-chaos systems is proposed. By means of discrete feedback with integratorfiltering, two hyper-chaotic systems with identical structure can be synchronized. Using this synchronizing method, securityof communication systems can be improved, thigh frequency components of transmitted signal can be screened out, and theeffect of disturbance on synchronization is reduced. The performance of this synchronizing approach is well illustrated bynumerical simulation experiment.
