Abstract

In order to improve the fairness of downlink non-orthogonal multiple access systems, this paper proposed a dual layer squeezing iterative power allocation method based on fairness improvement. Firstly, it designed a user channel splitting process based on user channel gain difference to facilitate dynamic adjustment of the degree of power squeezing. Secondly, it carried out the inner power squeezing iteration from strong users to weak users, and set the squeezing factor and additional squeezing factor according to the channel splitting situation, so that the weak users at the channel splitting point had a stronger squeezing degree towards the strong users. Thirdly, the reallocation and resqueeze of the inner power through outer iteration could further improve the fairness of power distribution, while maintaining the total power unchanged. The simulation results show that compared with the fairness index without channel splitting, it can improve the fairness with channel splitting by 25%; Compared to the situation that the squeezing factor and additional squeezing factor are only adjusted without the number of inner and outer iterations adjustment, it improves the fairness index performance by 53.71%. Meanwhile, the fairness of proposed algorithm is better than the waterfilling algorithm and gained a good fairness effect.
