摘　　要：针对泛在通信和万物智联的发展需求,地面5G蜂窝通信系统和非地面网络系统实现优势互补、融合发展、资源共享。非地面网络是一种全新的形态,文中先讨论5G非地面网络系统元素及相关应用场景,接着根据5G基站的测试方法和一致性要求,来分析误差矢量幅度测试的方法及相关指标,通过自主设计的程序生成的测试波形与商业软件生成的测试波形进行比对,从信噪比、信道带宽以及子载波间隔三个方面分析其对误差矢量幅度的影响。为非地面网络设备的设计研发提供基于3GPP最新标准的测试方法,可为相关设备大规模量产节省开销。In order to meet the urgent needs of ubiquitous communication and intelligent connection of everything,the ground 5G cellular communication system and non-terrestrial network system realize complementary advantages,integrated development and resource sharing.Non-terrestrial network is a completely new form of communication system.In this paper,it will first discuss 5G non-terrestrial network system elements and related application scenarios.After this,the analysis of the error vector magnitude will be discussed according to the 5G base station test methods and radiated conformance testing.Finally,by comparing the test waveforms from self-designed program and commercial software,it shows how the signal-to-noise ratio,channel bandwidth and subcarrier spacing would impact error magnitude test.This paper provides the product design of non-terrestrial network equipment for the latest standards of 3GPP testing methods and save money for the volume production of related equipment.
