摘要/Abstract

摘要： 为解决非正交多址接入（NOMA）下行链路中因配对用户间的数据干扰导致系统误码率过高的问题，提出一种基于配对用户数据相关性的NOMA方案。发射端根据配对用户数据序列的非相关性估计用户序列的相位旋转角度，设计阈值自适应选择的信号处理方法，将用户比特序列的相位旋转标记以及叠加信号通过高斯信道下发至用户，并在接收端使用下行控制信息携带的旋转标记选择解码方法。仿真结果表明，该方案可降低星座图上叠加信号星座点之间的相互干扰，在增加较少运算量的情况下有效提高系统误码率性能和用户公平性。

关键词: 非正交多址接入, 相位旋转, 非相关性, 误码率, 公平性

Abstract: In order to solve the problem that the system Bit Error Rate(BER) is too high due to data interference between paired users in the Non-Orthogonal Multiple Access(NOMA)downlink,a NOMA scheme based on data correlation between paired users is proposed.The transmitting terminal estimates the phase rotation angle of the user sequence according to the non-correlation of the paired user data sequence,and designs a signal processing method for adaptive selection of the threshold.It sends the phase rotation mark and the superimposed signal of the user bit sequence to the user through the Gaussian channel,and the decoding method is selected at the receiving terminal by using a rotation flag carried by the downlink control information.Simulation results show that the scheme can reduce the mutual interference between the superimposed signal constellation points on the constellation diagram,and effectively improve the system BER performance and user fairness under the premise of adding a small amount of calculation.

Key words: Non-Orthogonal Multiple Access(NOMA), phase rotation, non-correlation, Bit Error Rate(BER), fairness
