Abstract
In this letter, we investigate the effect of feedback delay and channel estimation errors in a decode-and-forward (DF) cooperative network with relay selection. In particular, we consider a multirelay cooperative scenario, where the best relay is selected from a subset of relays that are able to decode the source information correctly. In the selection scenario, the destination terminal estimates the relay-to-destination (R → D) channel state information (CSI) and sends the index of the best relay to the relay terminals via a delayed feedback link. We investigate the performance of the considered scenario in terms of average symbol error rate (ASER) and asymptotic diversity order. Simulation results are presented to corroborate the analytical results.
