Optimal transmission policy of truncated cooperative ARQ protocols using opportunistic amplify and forward relaying
In cooperative automatic repeat request (ARQ), the retransmission can be done by the source or by a selected relay. We consider opportunisitic amplify and forward (AF) relaying. The selected relay offers the highest instantaneous signal to noise ratio (SNR) of the relaying link (source-relay-destination). We investigate the optimal combination of source and relays transmission for a destination using a selective combining (SC) or a maximum ratio combining (MRC) of all received signals. This optimization is based on the bit error probability (BEP) at the destination after K transmissions.
