  This letter presents a device-to-device (D2D) enabling cellular full-duplex
(FD) cooperative protocol using non-orthogonal multiple access (NOMA), where an
FD relay assists in relaying NOMA far user's signal and transmits a D2D
receiver's signal simultaneously. The ergodic capacity, outage probability, and
diversity order of the proposed protocol are theoretically investigated under
the realistic assumption of imperfect self and known interference cancellation.
The Outcome of the investigation demonstrates the performance gain of the
suggested protocol over conventional FD cooperative NOMA system.
