Abstract :
In this paper, we analyze the performance of two sub-optimal antenna selection strategies for single relay based selective decode-and-forward (DF) cooperative multiple-input multiple-output (MIMO) systems. We assume that the source-relay, relay-destination, and the source-destination channels follow the Rayleigh fading. We derive the closed-form expressions and the upper bounds of the symbol error rate (SER) for selective DF cooperative MIMO systems employing M-ary phase shift keying in both the antenna selection strategies. From the derived SER upper bounds, we extract the diversity orders of the system in both the selection strategies. The optimal power allocation for the source and relay is derived in both the selection strategies, which minimize the SER of DF cooperative MIMO system.
