Ergodic Rate and Outage Performance of Full-Duplex NOMA Relaying with Channel Estimation Errors and Low-Resolution ADCs

In this paper, we analyze the performance of a full-duplex (FD) cooperative non-orthogonal multiple access (C-NOMA) relaying system with an amplify-and-forward (AF) protocol in presence loopback interference FD transceivers. Particularly, by considering channel estimation errors and quantization noise low-resolution analog-to-digital converters (ADCs), accurate approximation expression for ergodic rate closed-form solution outage probability are derived, respectively. The validity theoretical results is verified Monte Carlo simulations, which show that both have deleterious effects on moderate high signal-to-noise ratios (SNR). second phase C-NOMA system, sum decrease at SNRs due to loop interference. When ADC dynamic range reaches certain level, more affected compared ADCs.
