Abstract
Diversity is an effective technique in enhancing the link quality and increasing network capacity. When multiple antennas can not be used in mobile units, user cooperation can be employed to provide transmit diversity. In this paper, we analyze the error performance of coded cooperative diversity with multiple cooperating users over Nakagami fading channels under interference conditions. We derive the end-to-end bit error probability of coded cooperation (averaged over all cooperation scenarios). Results show that allowing more cooperating users improves the performance of the network under low loads, where two cooperating users suffice for highly loaded networks. Furthermore, the gains obtained by increasing the number of cooperating users decreases with increasing the network load.
