论文摘要
在本文中，我们提出了一种物理层安全方案，该方案利用人工噪声（AN）确保了下行链路合法的通信并将能量转移到在非合作性的非官方多次多孔（NOMA）场景下运行的节点。节点采用联合时间切换和动力开关方案来最大化收获的能量。我们为优化参数提供必要的分析和推导，并找到优化的传输参数，这些参数可以最大程度地提高用户之间的最低保密率，同时通过基于详尽的网格搜索来满足节点上最低传输能量和中断概率的约束。我们的分析和模拟证明了确保NOMA节点之间的通信的可行性，同时传递能量并满足停电概率限制。
In this paper, we present a physical-layer security scheme that exploits artificial noise (AN) to secure the downlink legitimate communications and transfer energy to nodes operating under non-cooperative non-orthogonal multiple-access (NOMA) scenario. The nodes employ a joint time-switching and power-switching scheme to maximize the harvested energy. We provide necessary analysis and derivations for the optimization parameters and find the optimized transmission parameters that maximize the minimum secrecy rate among users while meeting constraints on minimum transferred energy and outage probabilities at the nodes through an exhaustive grid-based search. Our analysis and simulations prove the feasibility of securing the communication among NOMA nodes, while transferring energy and meeting outage probability constraints.
