摘　　要：文章主要研究在硬件受限条件下,协作3D大规模MIMO传输系统的性能。通过理论分析和评估,探讨了基于非理想信道条件下硬件受限对通信系统性能的影响。基于莱斯衰落信道模型,研究了发送天线和接收天线硬件损伤对系统性能的影响,并推导出了频谱效率的闭式表达式,同时分析了在不同信噪比条件下的渐近性能。仿真实验结果表明,硬件损伤程度与系统频谱效率呈负相关,即硬件损伤越小,系统频谱效率越高。此外,使用较低质量的发送天线硬件对系统频谱效率的影响较小。This article mainly studies the performance of collaborative 3D massive MIMO transmission systems under hardware limitations.Through theoretical analysis and evaluation,the impact of hardware limitations on communication system performance under non ideal channel conditions was explored.Based on the Rayleigh fading channel model,the impact of hardware damage to the transmitting and receiving antennas on system performance was studied,and a closed form expression for spectral efficiency was derived.The asymptotic performance under different signal-to-noise ratio conditions was also analyzed.The simulation experiment results show that the degree of hardware damage is negatively correlated with the system spectral efficiency,that is,the smaller the hardware damage,the higher the system spectral efficiency.In addition,the use of lower quality transmitting antenna hardware has a relatively small impact on the system's spectral efficiency.
