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.
