Abstract: Abstract In order to improve the reliability of the cooperative communication system, a new collaborative Hybrid-ARQ protocol is proposed by combining the distributed codes with the averaged diversity combining technique. In the destination terminal, the retransmission information of relay is processed by incremental redundancy techniques, and the Chase combining technique is used to process the source information. Joint soft decision decoding is adopted at the destination terminal. In this paper, we give a lower bound of the outage probability expressions and simulation results. It is shown that the outage probability is deduced, and the average capacity is improved. Compared with these protocols which use Chase combining or incremental redundancy combining only, the new protocol can achieve better performance of outage probability and average capacity on rayleigh fading channel.
