摘要
大规模阵列天线技术可用于解决下一代无线通信的频谱有效性和功率有效性问题,对大规模阵列天线成形性能进行了仿真,得出了天线数目增加对均匀线阵方向图成形的影响,并通过计算比较了不同规模天线阵列的波瓣宽度,并仿真分析了不同规模均匀圆阵的方向图,最后研究了信道估计准确度对大规模天线阵列方向图成形性能的影响,仿真得出了信道估计矩阵存在误差时阵列天线方向图的变化。
Massive antenna array can be used to improve the efficiency of power and spectrum. Based on the simulation of massive antenna array, the parttens and beamforming performance of ULA with different sizes are analyzed, and the beamwidth of major lobe is calculated. Furthermore the patterns of UCA are compared while the number of antennas is increasing. Finally, the relationship between channel estimation and beamforming performance is researched, and the pattern results are simulated when the estimation error exists.
