混合量化下大规模多输入多输出的非正交多址接入系统性能研究
Performance analysis of massive MIMO-NOMA system with mixed quantization
摘要
Abstract
Unmanned aerial vehicle(UAV)can be used as amplify-and-forward(AF)relay in wireless communications systems.To improve the performance of UAV communication,a full-duplex(FD)massive multiple-input multiple-output(MIMO)non-orthogonal multiple access(NOMA)transmission scheme with mixed-resolution analog-to-dig-ital converters(ADCs)is proposed,and UAV provides services to ground users in a hovering state.In this paper,maximum ratio combining/maximum ratio transmission(MRC/MRT)is adopted and the influence such as imper-fect successive interference cancellation(SIC)is considered,the performance of the model is investigated and ana-lyzed with the spectral efficiency(SE)and energy efficiency(EE).The simulation results show that the perform-ance of the system is related to the number of antennas,the transmitted power of users,and the quantization bits.In addition,the advantages of systems equipping with mixed-resolution ADC are also demonstrated.关键词
