Abstract

Synchronization plays an important role in chaotic communications because it offers a potential advantage over noncoherent detection. In this paper we studied the synchronization of two coupled chaotic Colpitts circuits with linear error feedback scheme. The error dynamic system of the two coupled circuits was studied and the nonlinear junction in it was linearized for the sake of simplifying the problem. Based on a generic criterion of global chaos synchronization between two coupled chaotic systems from a unidirectional linear error feedback coupling approach, this paper derived the sufficient conditioner two coupled Colpitts circuits to obtain synchronization. Circuit simulations haw been carried out to verify the results
