英文摘要: |
A cooperative full-duplex (FD) non-orthogonal multiple access (NOMA) network is considered, 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 Nakagami-m 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 sum-rate 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 investigated. It is shown that the usage of NOMA with FD relaying outperforms the half-duplex (HD)-NOMA and conventional orthogonal multiple access (OMA) network when the self-interference is not too large. |
