Full-Duplex Non-Orthogonal Multiple Access Cooperative Overlay Spectrum-Sharing Networks With SWIPT

This article proposes a novel non-orthogonal multiple access (NOMA) assisted cooperative spectrum-sharing network, in which one of the full-duplex (FD) secondary transmitters (STs) is chosen among many for forwarding primary transmitter's and its own information to receiver receivers, respectively, using NOMA technique. To stimulate ST conduct transmission sustain operations, simultaneous wireless power transfer (SWIPT) technique utilized by harvest signal's energy. In order evaluate proposed system's performance, outage probability system throughput networks are derived tight closed-form approximations. Further, sum rate optimization problem formulated network rapid convergent iterative algorithm obtain optimized allocation coefficients. Numerical results show that FD, SWIPT, techniques greatly boost performance terms probability, throughput, compared half-duplex conventional orthogonal access-time division networks.
