In this paper, we investigate the performance of cooperative non-orthogonal access (NOMA) network with energy harvesting, where, source node and relay node serving as energy-constrained nodes harvest energy from the power beacon PBS. Source sends the superposed message towards the nearly-located user and relay via NOMA principle. The relay superposes and forwards the decoded signal and its own signal to the far-located user and the destination according to NOMA protocol. To measure the performance of the system quantitatively, we derive the exact closed form expressions for the outage probabilities of the near user, far user, and destination respectively over Rayleigh fading channels. Simulation results show that the reasonable power distribution coefficient and the increasing of transmission power of the power beacon improve the performance of cooperative NOMA network.
Key words: Cooperative transmission / NOMA / Energy harvesting / Outage performance
