论文摘要
在本文中，我们研究了大规模多输入多输出（MIMO）非正交多访问（NOMA）系统的下行链路的节能功率分配。在我们提出的方案中，我们将一个细胞分为两个区域。第一个区域是给用户，其距离基站（BS）的距离小于单元半径的一半，而第二个区域是用户与BS的距离超过单元半径的一半以上的用户。基于用户与BS的距离以及每个区域中的用户数量，我们为每个用户献有一定的功率。我们还使用标准干扰函数（SIF）提出了一种新的迭代算法来解决优化问题并获得最佳功率分配方案。仿真结果表明，所提出的算法从能源效率（EE）的角度优于其他算法。
In this paper, we investigate energy-efficient power allocation for the downlink of the massive multiple-input multiple-output (MIMO) non-orthogonal multiple access (NOMA) systems. In our proposed scheme, we divide a cell into two zones. The first area is for users whose distance from the base station (BS) is less than half of the radius of cell and the second area is for users whose distance from BS is more than half of the radius of cell. Based on distance of users from BS and the number of users in each area, we dedicate an amount of power for each user. We also use standard interference function (SIF) to propose a new iterative algorithm to solve the optimization problem and obtain the optimal power allocation scheme. Simulation results show that the proposed algorithm outperforms other algorithms from the energy efficiency (EE) point of view.
