【 摘 要 】

This paper studies a non-linear energy harvesting (EH) enabled full-duplex (FD) cooperative non-orthogonal multiple access (C-NOMA) system, where the near user acts as an FD relay to assist the transmission from BS to far user with power-splitting (PS) protocol. We derive the close-form expressions of outage probability in this considered system, and also give the asymptotic outage probability under high signal-to-noise ratio (SNR) regime. Additionally, we obtain the optimal power allocation parameter to minimize the outage probability, and discuss the impact of self-interference (SI) on outage performance. Moreover, it is observed from simulation results that the presence of SI improve the outage performance, which is caused by the so-called self-energy recycling.
