摘　　要：面向5G毫米波大规模阵列天线基站,创新提出了端到端性能测试系统。从技术原理、硬件架构、系统校准这几个维讨论了如何完成毫米波基站的性能验证。依据3GPP定义的信道模型,仿真了暗室静区中的最关键指标角度功率谱相似度百分比,并且给出了指标建议。A novel end-to-end performance testing system is proposed for 5 G millimeter wave(mm Wave)base station with massive antenna arrays in this paper.How to accomplish the performance test for mm Wave base station is discussed in terms of technical principles,hardware architecture and system calibration.Based on the channel model defi ned in the 3 GPP specifi cation,the similarity percentage of the power angle spectrum is simulated as the most important key metric in the darkroom zone,and then the metric is suggested.
