Secrecy Achievable Rate of Two-Way Illegitimate Full-Duplex Relay-Assisted NOMA with CCI

This paper investigates the adverse effects of co-channel interference (CCI) on the secrecy achievable rate (SAR) performance of illegitimate decode-and-forward full-duplex two-way relaying in power-domain non-orthogonal multiple access network. So as to minimize the information leakage, the investigation considers that illegitimate relay terminals are affected by a limited number of friendly jammers. In an effort to minimize the system overhead, the investigation activates a single illegitimate relay terminal by selecting a relay, which has the minimum secrecy achievable rate and maximizing. Obtained results reveal that while the CCI has adverse effects on system SAR performance, the friendly jammer helps to enhance the system performance. Monte-Carlo-based extensive simulations verify the numerically obtained results.
