Performance analysis of a decode-and-forward scheme under physical layer security over Rician fading channel

In this paper, we propose and evaluate the performance of the decode-and-forward scheme under physical layer security over Rician fading channel. The best relay is chosen to help the source to transmit data signals to the destination based on achievable secrecy rate (ASR) following criterions as: maximum first-single-hop, maximum second-single-hop and maximum dual-hop. The system performance is exactly evaluated by the outage probability of the ASR. The Monte-Carlo results are presented to verify the theoretical analysis.
