Physical Layer Security of Multi-user Full-Duplex One-Way Wireless Relaying Network

This paper investigates the physical layer security of the orthogonal frequency division multiplexing based wireless relaying network. The investigation considers a multi-user untrustworthy amplify-and-forward based one-way full-duplex wireless relaying network in the system model. According to the Monte-Carlo simulation results, the friendly jammers severely affect the system achievable secrecy outage probability performance and degrade the system performance curves in high signal-to-noise ratio regimes. Results also show that the system model that contains a large number of user-pairs achieves better secrecy performance in comparison to a small number of user-pairs.
