EKF Based Dual Synchronization of Chaotic Colpitts Circuit and Chuas Circuit
In this paper, dual synchronization of a mixed system containing a chaotic Colpitts circuit and a Chuas circuit, under an additive white Gaussian noise (AWGN) channel, will be studied by numeric simulations. The extended Kalman filter (EKF) is employed as the response system to achieve the dual synchronization. Two methods are proposed and investigated. The first method treats the combination of a Colpitts circuit and a Chuas circuit as a higher dimensional system, while the second method considers the Colpitts circuit and the Chuas circuit separately and utilize the cross coupling scheme. The simulation results indicate that the proposed methods can effectively achieve and maintain dual synchronization of the mixed system in AWGN channel.
