摘　　要：阐述无人机通信场景的特点,探讨建立3D-MIMO单球体几何信道模型的设计,并用Kronecker分析模型分解生成信道矩阵。在此基础上,采用递增、递减和最大范数三种经典天线选择算法,在无人机通信场景下进行验证。仿真结果表明,通信系统容量同信噪比有相同的增减趋势,并且在天线数量较小时,递增天线选择算法优于其他两种算法。This paper describes the characteristics of unmanned aerial vehicle communication scenarios,explores the design of establishing a 3D MIMO single sphere geometric channel model,and uses Kronecker analysis model decomposition to generate channel matrices.On this basis,three classic antenna selection algorithms,namely increasing,decreasing,and maximum norm,were used for verification in unmanned aerial vehicle communication scenarios.The simulation results show that the communication system capacity has the same trend of increase or decrease as the signal-to-noise ratio,and when the number of antennas is small,the incremental antenna selection algorithm is superior to the other two algorithms.
