Abstract
Considering non-orthogonal multiple access (NOMA) and orthogonal multiple access (OMA), this study explores device-to-device (D2D) communication networks with N full-duplex (FD) or half-duplex (HD) users, as well as a source node S transmitting signal and energy using a power-splitting (PS) scheme. Analytical expressions for the ergodic rates of the uplink and downlink links are derived under independent Rayleigh fading channels, and they are verified through Monte Carlo simulation. In contrast to the conventional HD mode, employing optimal serial interference cancellation and self-interference suppression techniques in FD significantly enhances spectral efficiency, achieving nearly double the gain. Furthermore, adjustments to the uplink and downlink ergodic rates can be accomplished by varying the PS parameter.
