Cooperative non-orthogonal multiple access (NOMA) system employs user relaying to enhance performance. Although full-duplex (FD) user relaying scheme does not incur additional bandwidth for relaying, the imperfect self-interference cancellation degra

Physical layer network coding (PNC) has been proposed for information exchange between a pair of users assisted by a relay. However, the spectral efficiency of PNC reduces when the number of user pairs increases due to the requirement of orthogonal c
