On the Performance of the Relay–ARQ Networks
Behrooz Makki, Thomas Eriksson, Tommy Svensson · IEEE Transactions on Vehicular Technology · 2015
This paper investigates the performance of relay networks in the presence of hybrid automatic repeat request (ARQ) feedback and adaptive power allocation. The throughput and the outage probability of different hybrid ARQ protocols are studied for independent and spatially correlated fading channels. The results are obtained for the cases where there is a sum power constraint on the source and the relay or when each of the source and the relay are power-limited individually. With adaptive power allocation, the results demonstrate the efficiency of relay-ARQ techniques under different conditions.
