摘要

摘要: 该文针对应用非正交多址接入(NOMA)技术的多输入多输出(MIMO)下行通信系统，在考虑误差传播进行理论分析的基础上，提出一种基于距离和空间相关度的用户匹配准则，并对基站的发射功率分配进行优化。仿真结果表明，所提方法能够在提高系统可容纳用户数的同时保证好的系统的和速率性能。

Abstract: A Multiple-Input Multiple-Output (MIMO) downlink communication system employing Non- Orthogonal Multiple Access (NOMA) technique is studied. Based on the theoretical analysis taking error propagation into account, a distance and spatial correlation based user matching criteria is proposed. In addition, the allocation of the base stations transmit power is optimized. Simulation results show that the proposed method can increase the number of subscribers that the system can accommodate, while guaranteeing good systems sum-rate performance.
