BER Analysis For 2×2 Mimo High-Efficiency DCSK System

This paper investigates a chaotic communication system based on the combination of high-efficiency differential-chaos-shift-keying (HEDCSK) scheme and multiple-input multiple-output technique, which aims at exploiting multi-path propagation to improve the system performance. Operation and discrete model of the system with the use of modulation/demodulation of HEDCSK and Alamouti space-time coding/decoding for 2×2 antennas are described. The bit error rate (BER) in the presence of an additive white Gaussian noise (AWGN) and Rayleigh fading is theoretically analyzed and verified by numerical simulations. Obtained results show the improvement of the BER performance of the proposed scheme compared to other related systems.
