description | Non-orthogonal multiple access(NOMA) has been widely used in the research of the fifth generation communication,due to the advantages of improving the spectrum efficiency and data rate.In order to guarantee the service of users,a new power allocation strategy was proposed to improve the fairness of users in the cell edge.According to the proportional fairness method,the goal was to maximize the proportionality fairness factor among the users with the least fairness in multiplexed users.The nonconvex objective function was transformed into convex function,and the optimal solution of problem was obtained by KKT optimal constraint condition.Simulation results show that the new NOMA-based power allocation strategy proposed outperforms the traditional orthogonal multiple access technology (OMA). |
