Abstract: User cooperation provides transmit diversity even when mobile users cannot possess multiple antennas due to size constraints. Recently, a kind of user cooperation scheme called coded cooperation was proposed, in which standard channel coding methods were used to implement cooperation. This scheme achieves remarkable gains compared to non-cooperative system and other cooperation diversity scheme (such as amplify-and-forward and decoded-and-forward) while maintaining the same information rate and transmit power. In this paper, we propose a new coded cooperation Algorithm. We compare the performance of our scheme with coded cooperation proposed by Hunter under a variety of conditions in slow fading, and a significant improvement is achieved.
