摘　　要：为了提高蜂窝网络非正交多址接入系统的能量效率,减少功率消耗,提出了一种基于系统能量效率最大化的非正交多址接入系统功率分配算法。通过对数学模型的分析,在满足一定条件下,将多用户非正交多址接入系统的功率分配问题转化为系统容量最大化问题进行求解;当条件不满足时,给出了通过次梯度法和障碍函数法进行求解的方法。仿真结果表明:该算法与现有方法相比具有显著的性能提升。In order to improve energy efficiency and reduce power consumption,a non-orthogonal multiple access(NOMA)power allocation algorithm based on system energy efficiency maximization is proposed for NOMA systems in cellular networks.The multi-user NOMA power distribution problem is transformed into system capacity maximization problem by analyzing the mathematical model under certain conditions.When the conditions are not satisfied,the subgradient method and obstacle function method are used to solve the problem.Simulation results show that the proposed algorithm has significant performance improvement compared with existing methods.
