METHOD AND SYSTEM FOR CHARACTERIZING A RADIO CHANNEL OF A WIRELESS NETWORK USING VARIABILITY OF SYNCHRONIZATION

摘要

A speed parameter or chan-nel quality parameter are determined in a mobile device based on variation in fre-quency offset measurement. A higher vari-ation in the frequency offset measurement reflects a poorer channel quality and a higher speed; a lower variation in the fre-quency offset measurement reflects a better channel quality and a lower speed. The pa-rameter(s) may be fed back to the system and used, for example, to make adaptive modulation and coding decisions.
