摘要/Abstract

摘要： 针对多簇且每个簇包含任意用户的下行非正交多址接入（NOMA）系统，提出了一种最大化系统能量效率的功率分配方案.首先推导了满足所有用户连续干扰消除需求的情况下，单个用户及单个簇所需的最低功率，建立最大化系统能量效率的用户间功率分配优化问题，然后采用二分法求解最大化单个簇内能量效率的功率分配优化问题，基于该结论将最大化系统能量效率的用户间功率分配优化问题转换为簇间功率分配优化问题，最后给出了一种迭代的簇间功率分配方案，并根据簇间功率分配的结果为单个用户分配功率.仿真结果表明，所提方案的系统能量效率高于相同场景中的已有方案.

Abstract: A power allocation scheme to maximize energy efficiency is proposed for downlink non-orthogonal multiple access(NOMA)system with multiple clusters and each cluster containing arbitrarily user. Firstly,the minimum powers required for a single user and a single cluster are derived to meet successive interference cancellation. The optimization problem of power allocation among users is established to maximize the energy efficiency of the system. Then,the power allocation optimization problem of maximizing the energy efficiency of a single cluster is solved by using bisection method. Based on this conclusion,the optimization problem of power allocation among users to maximize the energy efficiency of the system is transformed into the optimization problem of power allocation among clusters. Finally,the power for each user is obtained according to the inter-cluster power allocation,which is get by an iterative scheme. Simulations show that the energy efficiency of the proposed scheme is better than that of the existing scheme in the same scenario.

Key words: non-orthogonal multiple access, energy efficiency, successive interference cancellation, bisection method, power allocation
