摘要

针对非正交多址(NOMA)系统的下行链路，提出了合法用户的功率分配方案。重视5G的物理层安全和绿色要求，首先定义了保密能效(SEE)。然后，我们制定了一个优化问题，其中确定了每个用户的功率分配因子和总功率分配因子。为了降低计算复杂度，我们将优化问题解耦为两个连接的子问题，逐个求解。最后，给出了一些数值结果来验证我们提出的功率分配算法。

Secrecy Energy Efficiency Maximization in a NOMA System

In this paper, for the downlink of a non-orthogonal multiple access (NOMA) system, the power allocation scheme is proposed for the legitimate users. Attaching importance to the physical layer security and the green requirements of 5G, the secrecy energy efficiency (SEE) has first been defined. Then, we formulate an optimization problem, where each user's power allocation factor and total power allocation factor are determined. For reducing the computational complexity, we decouple the optimization problem into two concatenate subproblems and solve them one by one. Finally, some numerical results are presented to validate our proposed power allocation algorithm.
