Abstract:


In this paper the performance of a cooperative wireless communication system based on combined best relay selection (BRS) and adaptive LDPC coded modulation (ACM) scheme is investigated. These investigations are focused on evaluating the performance of the proposed cooperative wireless communication system over independent non-identical Rayleigh fading channels in terms of bit-error rate (BER) using MATLABĀ® computer simulations and comparing the system performance with ACM direct transmission and ACM cooperative with single relay. The simulations results show that the proposed cooperative scheme achieves lower signal-to-noise ratio (SNR) values for desired bit-error rate (BER) and high spectral efficiency as compared to ACM direct transmission and ACM cooperative with single relay.
