TY - JOUR JF - ITRC JO - VL - 11 IS - 2 PY - 2019 Y1 - 2019/6/01 TI - Wireless-powered Cooperative Spectrum Sharing Networks with Full-duplex and NOMA Transmissions TT - N2 - We consider a cooperative spectrum sharing non-orthogonal multiple access (NOMA) network, where a secondary transmitter assists transmission from a primary transmitter to a primary receiver with poor channel conditions, and at the same time transmits to a secondary receiver with strong channel conditions. The secondary transmitter is assumed to be energy-constrained and powered by an energy access point located in its vicinity. In order to cancel the self-interference at the full-duplex multi-antenna secondary transmitter, two zero-forcing (ZF)-based beamforming schemes and a maximum ratio combining/maximum ratio transmission scheme are designed and the corresponding outage probability analysis of the primary and secondary networks, are derived. Outage probability results are used to study the delay-constrained throughput of the system. Our results suggest that by using ZF-based beamforming schemes depending on the number of transmit/receive antennas at the full-duplex secondary transmitter significant performance improvement can be achieved compared to the half-duplex counterpart. Moreover, our results indicate that proposed ZF-based schemes achieves a zero-diversity order.
