In this paper the performance of Bit-interleaved Coded Modulation with Iterative decoding (BICM-ID) based multiple-relay cooperative system is analyzed over Nakagami-m Fading channels. The relays are operating in Amplify-and-forward (AF) mode. The Moment generating function (MGF) based approach is used to obtain the theoretical error-free feedback (EF) bounds. The results show that a significant gain is obtained in the performance of the system due to cooperative and code diversities by introducing Cooperating relays and Bit-interleaved Coded Modulation with Iterative decoding. The performance of bit-interleaved low-density parity-check Coded Modulation with Iterative decoding (BILDPCM-ID) based cooperative system, using low-density parity-check (LDPC) code instead of convolutional code, is also analyzed in term of bit-error rate (BER). The Performance comparisons of BICM-ID and BILDPCM-ID based systems are shown using the Set partitioning (SP) labelling for 8PSK Modulation scheme. The BER curves are obtained by performing the Monte Carlo Simulation. ©2010 IEEE.
