Cooperative communications enable single antenna mobiles in a multi-user environment to share their antennas and form a virtual multiple antenna array that allows them to achieve transmit diversity. In order to achieve improved diversity over the classical coded cooperation method in fading channels, we consider a coded cooperation diversity strategy that is suitable for multiple relays channels. We derive a finite range single integral solution for the outage probability, which characterize the coded performance with multiple relays at various rates. Numerical results demonstrate the merits of coded cooperation and other repetition-based methods, under various relay and uplink channel conditions, and show that it achieves the full diversity order.
