摘要：

In this letter, we propose an energy harvesting (EH) based incremental relaying cooperative non-orthogonal multiple access (IR-EH-NOMA) protocol, considering two user downlink network. We derive analytical expressions for the system throughput of IR-EH-NOMA network and conventional cooperative relaying NOMA network with EH (CR-EH-NOMA network) in the delay limited transmission mode, considering imperfect successive interference cancellation (i-SIC) and maximal ratio combining (MRC). We also derive expressions for the optimal power splitting (OPS) factors at the relay that maximizes the asymptotic throughput of the considered systems. Numerical and simulation results are described to establish the supremacy of IR-EH-NOMA system over CR-EH-NOMA system in terms of outage and throughput.
