Abstract

In this paper, we analyze performance of the inband full-duplex amplify-and-forward one-way relay system in which two terminal nodes operate in the half-duplex mode while the relay node in the full-duplex mode. Unlike previous works we consider the case of imperfect loop-interference cancellation at the full-duplex relay and assume that the direct link between the source and the destination nodes exists in the system. We show that the system performance in the case with the direct link is significantly improved over the case without this link. Using theoretical analysis we can obtain the closed-form of the approximate outage probability, throughput, achievable capacity and symbol error probability of the system. Based on this analysis an effective power allocation for the full-duplex mode is derived to improve the system performance. Numerical results are compared with simulated ones for different levels of residual loop-interference to verify the theoretical analysis. © 2018 IEEE.
