一种新型的VDT+OTA测试方法——在实验室中重建无线电场环境

One novel VDT+OTA test method to reproduce field radio environment in lab

介绍了一种新型的实验室测试方法,实现了在实验室中重建无线电场信道数据,并以采集到的场数据为例评估了时分双工长期演进用户设备的性能。首先,提出了基于采集回放仪的场测量方法。接着介绍了能够产生实验室回放文件的精确建模方法,该方法支持基于信道仿真器的多探头暗室测试方案。最后,给出了以吞吐量为关键业绩指标的实验室测试结果,从而实现了面向用户体验的第四代移动通信技术用户设备性能测试。

This paper introduces a novel in-lab test method to reproduce a field radio channel data in lab,and it uses recordedfield data as an example to evaluate TDD-LTE UE performance.Firstly,it presents the field measurement method based on thescanner;and then it introduces accurate modeling way as conversion to generate in-lab playback file and also mapping to sup?port CE based MPAC test solution;at last it shows in-lab throughput result as KPI to fulfill end-user experience oriented4GUE performance test.
