基于数据预测的手机总全向灵敏度(TIS)的快速测试

A Fast Measuring Method for Total Isotropic Sensitivity for Mobile Phones Based on Data Predication

手机总全向灵敏度(TIS)是OTA测试的重要指标之一。而基于CTIA的步进测试法,测试非常耗时。本文在深入研究基站发射功率和误码率关系的基础上,得出具有一定通用性的拟合函数,进而提出了一种基于数据预测的TIS测试方法。通过编写相应自动测试软件,实现快速测试。该法将大大提高测试效率,有很高的应用和推广价值。

Total Isotropic Sensitivity（TIS） is one of the vital indexes of OTA test,but it＇s time-consuming based on the stepping test technique of CTIA.In this paper,we gained a universal fitting function after lucubrating the relationship between cell power and BER,then a measurement method based on data predication is put forward.After compiling relevant automatic testing software,fast-measuring can be achieved.This technique can greatly improve the measurement efficiency and has huge application value.
