摘要

A cooperative full-duplex(FD)non-orthogonal multiple access(NOMA)network is consid-ered,in which a source communicate with multiple users via multiple energy harvesting(EH)FD relays.Based on this structure,a novel relay selection scheme is proposed over Nakagamim fading channels by considering both the channel state information(CSI)and the energy statuses of relays.A finite Markov chain is adopted to capture the evolution of relay batteries and simplify the performance analysis by making some reasonable assumptions.General closed-form expressions of the outage probability and the ergodic sumrate are derived.All the theoretical results are validated by Monte-Carlo simulations.The impacts of various system parameters,such as the number of relays,the self-interference(SI)at the involved relay and battery size,on the performance are extensively investi-gated.It is shown that the usage of NOMA with FD relaying outperforms the half-duplex(HD)-NO-MA and conventional orthogonal multiple access(OMA)network when the self-interference is not too large.
