Abstract

In this paper, the outage performance is studied for a full-duplex (FD) relay network that adopts an amplify-and-forward (AF) scheme. The residual self- interference (RSI) generated by a relay node is treated as a useful signal, rather than noise as in the existing works, at a destination node. We provide a new approximate closed-form expression for the outage probability with the knowledge of the instantaneous source-relay (SR) channel gain, and an optimal power allocation (OPA) scheme to further improve the performance by minimizing the derived outage probability in hand. The analytical results are validated through numerical simulations, which reveals that the proposed FD scheme can outperform the conventional half-duplex (HD) and FD schemes in the AF relay networks.
