Ota Performance Test Method For Wireless Communication Terminal

First, based on the wireless communication terminal of OTA test in testing principles, the uncertainty analysis, data acquisition and data analysis, to research and comparison, summarization and defines to the data acquisition method of OTA test. Confirmed the test method of dissertation was the same method to actual testing. Secondly, according to the uncertainty analysis and statistics theory, from discrimination, stability, bias, linearity, repeatability and reproducibility of the measurement system analysis to existing OTA system, confirm the existing darkroom of OTA testing is reliable and accurate, to ensure the dissertation used by the experimental data obtained are reliable and effective from the existing darkroom of OTA test. Then, through normality inspection and non-parametric test method (diverse samples Kruskal-Wallis inspection and diverse samples of Moon median inspection)of statistics theory and method, the authors use Mintab to auxiliary calculation and test on the four OTA Angle of spherical coordinates of Theta axis and the Phi axial spacing stepping angle to measurement data analysis and judgments, confirm interval stepping angle for 5 degrees,10 degrees.15 degrees and 30 degrees when measured data of mean value is equal to the four dimensions, i.e., the test results are equivalent; At last, the author with interval stepping Angle 15 degrees and 30 degrees as optimal test method, combining with the basis of uncertainty, the theoretical and experimental results, to construct the whole data analysis, from the frame-chart experimental principles and data analysis angle realized to tested the system optimization.
