Description:

In this paper, dual synchronization of a hybrid system containing a chaotic Colpitts circuit and a Chua's circuit, connected by an additive white Gaussian noise (AWGN) channel, is studied via 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 Chua's circuit as a higher-dimensional system, while the second method considers the Colpitts circuit and Chua's circuit separately and utilizes the cross-coupling scheme. The simulation results indicate that the proposed methods can effectively achieve and maintain dual synchronization of the hybrid system through an AWGN channel.
