Particle Filter Based Synchronization of Chaotic Colpitts Circuits Combating AWGN Channel Distortion
In this paper synchronization of chaotic Colpitts circuits using particle filter (PF) to combat additive white Gaussian noise (AWGN) channel effect, will be studied by numeric simulations. A novel PF algorithm suitable for chaos synchronization is proposed. With this algorithm, chaos synchronization of Colpitts circuits can be achieved and maintained in channels with AWGN. Parameters in the proposed PF algorithm are studied to understand their effects on the synchronization performance. Synchronization performance using the proposed PF algorithm is compared with those using other digital filters, such as extended Kalman filter (EKF), PF with systematic resampling method. It is found the proposed PF algorithm over performs the other digital filters. Simulation results also show that the particle number is not very critical to the synchronization performance when this PF algorithm is used.
