Abstract

To enable full-duplex cooperative communications using half-duplex relays a bu?er-aided relay selection scheme based on amplify-and-forward (AF) is proposed in this work that can fully exploit the diversity gain The key idea is to always select di?erent relays to receive and transmit in the same time slot Since the receiving relay is interfered by the transmitting relay we apply a previously proposed interference cancellation scheme to mitigate the inter-relay interference (IRI) Through simulations we study the performance of the proposed scheme under di?erent scenarios and discuss the impact of various system parameters including the bu?er size the number of relays and the signal-to-noise ratio (SNR) Di?erent bu?er management trategies are also investigated
