Performance Analysis Of Chaotic Communications In Cooperative Cellular System

Abstract — The Differential Chaos Shift Keying (DCSK) modulation and demodulation is designed and simulated. The DCSK cooperative communication system for two users is proposed in this paper. The single relay cooperative network with amplify-and-forward relay is investigated in DCSK system according to two cooperation protocols, namely, conventional cooperation. Simulation results demonstrate that, through a conventional cooperation mechanism, the DCSK-CC system has better bit error rate. In addition, BER performance of DCSK in cooperative scenario is analyzed over a Rayleigh fading channel. Improved BER rates and diversity gains are the products of employing the above suggested techniques.
