Abstract
In this letter, we study a power-domain non-orthogonal multiple access (NOMA) system in which a base station (BS) superimposes the transmit signals to the users. To enhance spectral efficiency and link reliability for the far-distance user, a full-duplex (FD) relay assists the BS while the near-distance user is reached over the direct link. For this setting, we analyze outage probability and sum rate of the NOMA system over Nakagami- $m$ fading with integer fading severity parameter $m$ . Numerical results are provided for outage probability and sum rate to show the effect of system parameters on the performance of the FD NOMA system over Nakagami- $m$ fading.
