A Measurement Method based on Time-Frequency Representations for Testing GSM Equipmen

[ptt3i]

A digital method for the measurement and characterization of Global System for Mobile Communications (GSM) equipment is presented here. The method, based on the use of time-frequency representations, shows itself suitable to carry out a whole range of measurements needed for compliance tests both for base stations and mobiles. It is so possible to avoid the employment of different instruments, complex procedures, and qualified users. Some aspects regarding GSM measurements are first presented to clearly describe the operative stages of the method. Then, its performance is assessed by analyzing reference signals. Experimental results obtained from the application of the method to actual GSM signals are finally given
