摘　　要：本文针对相同天线数目下,二维方形阵和三维立方体阵的信道容量对比。通过推导两种阵列的方向矩阵和角度功率谱,得到信道矩阵,从而求解信道容量。仿真结果表明:相同条件下,三维阵列的信道容量远高于二维阵列。The thesis compares the capacity of two-dimensional square array and three-dimensional cubic array for the same number of antennas.The channel matrix H is obtained by deriving the direction matrix and the angular power spectrum of the two arrays,thereby solving the capacity"C".The simulation results show that under the same conditions,the capacity of the three-dimensional array is much higher than that of the two-dimensional array.

关 键 词：大规模MIMO阵列 信道 角度功率谱 信道容量
