Abstract

This paper studies an overlay network with non-orthogonal multiple access (NOMA) wherein the far-licensed NOMA user is assisted by either the near-licensed NOMA user or the unlicensed source to maintain its communications with the licensed NOMA transmitter. Both the near-licensed NOMA user and the unlicensed source implement practical nonlinear energy harvesters to meliorate energy efficiency. The performance metrics of the proposed overlay network with NOMA and EH (ONwNOMAEH) such as energy efficiency, system throughput, and outage probability are analysed in an explicit form. Multiple results expose the effectiveness and the flexibly adjusted performance of the proposed ONwNOMAEH.

具有非正交多址和能量收集的覆盖网络：性能评估

摘要

本文研究了一种非正交多址 (NOMA) 覆盖网络，其中远许可 NOMA 用户由近许可 NOMA 用户或未许可源协助，以维持与许可 NOMA 发射机的通信。接近许可的 NOMA 用户和未许可的来源都实施实用的非线性能量收集器来提高能源效率。以明确的形式分析了所提出的具有 NOMA 和 EH (ONwNOMAEH) 的覆盖网络的性能指标，例如能源效率、系统吞吐量和中断概率。多项结果揭示了所提出的 ONwNOMAEH 的有效性和灵活调整的性能。
