论文摘要
非正交的多重访问（NOMA）和合作继电器系统是满足未来无线网络（例如高光谱效率和广泛覆盖面积）要求的两种有希望的技术。另一方面，能源效率在具有有限的能源（例如传感器网络和/或物联网（物联网））的应用中也具有很高的优先级。为此，在本文中，我们提出了NOMA的无线功率合作继电器系统，从而提高了光谱和能源效率。我们考虑三种不同的能源收集（EH）协议（即功率共享（PS），时间共享（TS）和理想），对于所有三种EH协议，我们为所考虑的系统模型得出了可实现的速率。我们通过计算机模拟验证分析，并与基准相比，呈现无线动力系统的有效性。
Non-orthogonal multiple access (NOMA) and the cooperative relaying systems are two of the promising techniques to meet requirements of future wireless networks such as high spectral efficiency and wide coverage area. On the other hand, the energy efficiency has also high priority in the applications with limited energy such as sensor networks and/or internet of things (IoTs). To this end, in this paper, we propose wireless powered cooperative relaying system with NOMA thereby increasing spectral and energy efficiency. We consider three different energy harvesting (EH) protocols (i.e., power sharing (PS), time sharing (TS) and ideal) and for all three EH protocols, we derive achievable rate for the considered system model. We validate the analysis with computer simulations and present the effectiveness of wireless powered system compared to the benchmark.
