In this paper, we propose two adaptive cooperation protocols for wireless systems. The first protocol chooses between cooperative communications (CC) and non-cooperative communications (NCC), the protocol that offers the highest instantaneous throughput. The best relay is activated only if the instantaneous throughput of relayed link is larger than that of direct link. The second protocol chooses between CC and NCC, the protocol that maximizes the average throughput. The best relay amplifies the received signal only when the average throughput of relayed link is larger than that of direct link. Both protocols include adaptive modulation and coding to increase the throughput by selecting the appropriate modulation and coding scheme. The results are valid for Rayleigh fading channels where relay nodes use amplify and forward relaying. [ABSTRACT FROM AUTHOR] |
