摘要：

In this paper, we investigate the outage performance of a system combining techniques of non-orthogonal multiple access (NOMA) and full-duplex (FD) in cooperative communication over Nakagami-m fading channels. The NOMA-user with better channel condition play a role of a decode-and-forward (DF) relaying node to assist the NOMA-user with worse channel condition in forwarding its messages. The closed-form expressions for outage probability of two users are derived with a realistic assumption that residual self-interference (RI) suppression and successive interference cancellation (SIC) are imperfect. The mathematical results afford some insights into the impact of RI parameter, imperfect SIC coefficient and multipath fading factor on the system. The Monte-Carlo simulation results verify the accuracy of theoretical analysis and provide an clear system observation.
