Multiple-input multiple-output (MIMO) systems can be adopted in cooperative wireless networks to bring further space diversity or/and to improve the throughput of the system. In this paper, we evaluate the performance of MIMO applied to a turbo coded cooperation system. The considered system is studied under two scenarios where the sources transmit over either orthogonal channels or non-orthogonal channels. For the latter, interleave-division multiple-access (IDMA) is used for multi-source detection. We evaluate the performance improvement in terms of reliability (frame error rate) and efficiency (throughput efficiency), and determine the channel conditions where adopting MIMO in addition to cooperation is beneficial.
