• In Fig. 2, outage probability is evaluated by considering various number of relays (i.e. N), α=2bps/Hz, and .
• As shown in Fig. 3, in the FD mode, OPA scheme under SPC policy outperforms that under IPC policy in terms of coding gain by about 2 dB. As shown in Fig.
• As shown in Fig. 3, the EPA have appeared the floor effect by the residual interference powers and noise for outage probability at the high SNR. However, when the residual interference powers had been suppressed by power allocation, the OPA hasn’t appeared the floor effect for outage probability at the high SNR.
• , all substantially impact the performance of the multi-relay systems. Finally, simulation results showed that the FD based mode could outperform the HD based mode in terms of coding gain by more than 4 dB, provided that the self-interference at the FD relays can be sufficiently suppressed.
• Particularly, the theoretical analysis was shown to match the corresponding numerical results well. Furthermore, it was also shown in the numerical results that the other parameters, including the number of relays, the residual self-interference, and the SNR of relaying links, etc., all substantially impact the performance of the multi-relay systems. Finally, simulation results showed that the FD based mode could outperform the HD based mode in terms of coding gain by more than 4 dB, provided that the self-interference at the FD relays can be sufficiently suppressed.
• The performance of the FD based relay selection scheme under DF relaying mode was evaluated by deriving the closed-form expressions of the CDF, the PDF and the outage probability of the activated link. The proposed scheme with OPA scheme (under IPC and SPC policies) was also validated by using simulations.
