This paper focuses on decode-and-forward (DF) OFDM full duplex relaying (FDR) systems with multiple relays, where residual loop interference is taken into account. Closed-form and high-SNR approximate expressions for the outage probability are derived. Simulations are carried out to validate the derived outage performance and compare the performance of OFDM FDR with that of OFDM half duplex relaying...
Relaying has been regarded as an effective technique to meet the challenge of network coverage extension. Although relaying can improve cell-edge user performance, cell-center users may suffer serious interference from relay stations. Therefore, intra-cell interference and inter-cell interference have been two major problems which degrade the entire network performance under improper relay deployments...
In the presence of the primary user's interference, the outage probability of a dual-hop decode-and-forward (DF) cognitive relay network (CRN) over Rayleigh fading channels is investigated. We first derive the exact expression for the outage probability, using which the impact of different system parameters on the outage performance is presented in the asymptotic regimes. In addition, the asymptotic...
