Abstract
Integration of full-duplex (FD) technology with cooperative device-to-device (CD2D) communications system has recently emerged as a potential candidate for the fifth-generation (5G) and beyond technologies to improve the spectral efficiency of a cellular system. This paper investigates the outage performance of a multicarrier FD CD2D communications system wherein, the D2D link source node (S) serves as an FD relay for uplink cellular transmission. The self-interference (SI) occurring at S is suppressed using analog cancellation schemes, and the residual SI (RSI) is further suppressed using digital domain (DD) RSI cancellation techniques. A probabilistic mathematical model is established for the performance evaluation of the proposed system. The closed-form expressions for D2D and cellular outage probability are derived. Simulation results show that the proposed FD CD2D communications system, along with minimum mean square error-based DD RSI cancellation, gives the optimum performance compared to the least square-based RSI cancellation scheme.
