同步在混沌通信中扮演着重要的角色，因为它比非相干检测具有潜在的优势。本文研究了线性误差反馈方案下两个耦合混沌Colpits电路的同步问题。对两个耦合电路的误差动态系统进行了研究，并对其中的非线性结线性化，使问题简化。基于基于单向线性误差反馈耦合方法的两个耦合混沌系统全局混沌同步的一般判据，导出了两个耦合Colpits电路实现同步的充分条件。为了验证结果，进行了电路仿真
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
