An Efficiency Measurement Method for Total Isotropic Sensitivity Based on Data Predication
The total isotropic sensitivity (TIS) is one of important parameters of the mobile phone, and should be measured by developers and manufacturers. But measuring TIS would take a long time based on the stepping test technique of the Cellular Telecommunications A Internet Association (CTIA). The paper proposed an efficiency measurement method for TIS based on data predication. As the relationship between BER and Cell power is nonlinear, using exponential function, a math model is set up to describe this relationship. The unknown coefficients in the model can be determined by several sets of measurement data and the least square method. Then the TIS can be predicted using above math model Finally, fast automatic measuring software is designed and the measurement results show that the proposed method keeps the precision but the measurement time is only 1/3 of the stepping test technique.
