Self-Energy Recycling in DF Full-Duplex Relay Network

curity (PLS) reliability of concurrent wireless com-
munications. A decode and forward (DF) full-duplex
(FD) network with the impact of an eavesdropper was
proposed to evaluate the security and reliability. Es-
sentially, the DF-FD relay adopted the power-splitting
(PS) protocol to gather energy from the source and si-
multaneously utilized the self-energy recycling (S-ER)
technique by manipulating the loopback interference to
increase the harvested energy. By constructing closed-
form expressions for outage probability (OP) and in-
tercept 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 impor-
tant role in selecting the suitable trade-off for the pro-
posed system.
