Abstract

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.
