| Abstract: | This paper modifies the Drive Response chaotic synchronous method presented by Pecora and Carroll. Signals at the transmitter are sampled with their amplitude limited to drive the receiver, synchronization of two identical structure hyper chaotic systems is thus attained. The effect of amplitude limited and noise on chaotic synchronization is discussed. By using the synchronous method, the effect of large signal on the system is got rid of, security of the system is improved and resource is saved. The synchronization method is illustrated by numerical simulation. |
