Abstract
"In this paper, we mathematically investigate a downlink non-orthogonal mul tiple access (NOMA) system for short-packet communications (SPC) in which
the near users are used as full-duplex (FD) relays to forward intended signals
from the source to a far user. In addition, partial relay selection is employed to
enhance the performance of the FD relays under the impact of imperfect inter ference cancellation. At the far user, selection combining (SC) or maximal
ratio combining (MRC) is employed to combine the signals received from the
source and the selected FD relay. The analytical expressions for the average
block error rate (BLER) of two users over flat Rayleigh fading channels are
derived. Furthermore, closed-form asymptotic expressions of the average
BLERs at the near and far users in high signal-to-noise ratio (SNR) regimes
are obtained. The numerical results show that the analytical BLERs of the near
user and far user closely match the simulation results"
