Power allocation scheme for non-orthogonal multiple access system based on system energy efficiency maximization
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.
