Exploiting Incremental Virtual Full Duplex Non-Orthogonal Multiple Access Systems

This paper investigates the throughput performance of an incremental virtual full-duplex non-orthogonal multiple access (I-VFD-NOMA) communication system, where two energy harvesting (EH) enabled near users are willing to forward message for far user using decode-and-forward (DF) protocol. If direct link between source and exists, I-VFD-NOMA scheme is used save channel resources. does not exist, can be only VFD-NOMA used. With this structure, The analytical expressions system considering imperfect successive interference cancellation (I-SIC) selection combining (SC) derived when exists or not. aim maximizing throughput, expression optimal power splitting factor at also exist. All theoretical results validated by numerical simulations which demonstrate that proposed superior existing NOMA systems.
