Performance Evaluation of Non-Orthogonal Multiple Access with Energy Harvesting

The paper evaluates the system throughput of non-orthogonal multiple access with energy harvesting (NOMAwEH) subject to realistic considerations including nonlinear energy harvesting (NLEH), power beacon, fading, and path-loss. Towards this end, the paper proposes the performance evaluation of the system throughput metric for NOMAwEH accounting for these considerations. Various results unveil considerable performance mitigation due to channel impairments and NLEH. Moreover, the performance improvement increases with better channel conditions. Further, the proposed NOMAwEH outperforms significantly its orthogonal multiple access with energy harvesting counterpart.
