摘要

本文主要解决当前功率域单胞元非正交多址接入结构应用层面存在的问题.具体说，针对现有单胞元结构因多用户时频同传形成强干扰而导致边缘用户服务质量差的问题，利用资源正交化的组网策略构建中心用户频带独立正交、边缘用户与其频带合作共享的并行多胞元结构，并进一步利用中心用户可获取边缘用户先验知识的特征将全双工的协作通信机制引入其中，从而有效解决现有单胞元结构在译码复杂度以及用户公平性等方面存在的不足.仿真结果证实了所提方案的有效性.

Abstract

This paper aims to solve several underlying problems arising from the application of current single-cell power domain non-orthogonal multiple access (NOMA) structure.Specifically

to solve the problems lying in the current single-cell structure such as high decoding complexity

poor user fairness

and bad quality of service of cell edge users

this paper integrates NOMA technique with the orthogonal resource allocation strategy to present a parallel multiple-pairing operation unit

where the frequency band orthogonally allocated to each central user and the cell edge user share the total bandwidth by pairing with each central user to perform NOMA and a full-duplex cooperative communication strategy is further introduced to the central users for they have the priori-knowledge of the cell edge user.Simulation results verify the validity of the proposed scheme.
