Self-Energy Recycling in DF Full-Duplex Relay Network: Security-Reliability Analysis

This paper studied the physical layer security (PLS) reliability of concurrent wireless communications.A decode and forward (DF) full-duplex (FD) network with the impact of an eavesdropper was proposed to evaluate the security and reliability.Essentially, the DF-FD relay adopted the power-splitting (PS) protocol to gather energy from the source and simultaneously utilized the self-energy recycling (S-ER) technique by manipulating the loopback interference to increase the harvested energy.By constructing closedform expressions for outage probability (OP) and intercept probability (IP), we offer the trade-off analysis between them.Monte Carlo simulation was conducted to verify the analytical formulations.Furthermore, the key parameters were also examined to play an important role in selecting the suitable trade-off for the proposed system.
