摘要：
A method and a corresponding apparatus tor receiving a signal over a wireless communications channel, making a plurality of frequency offset measurements in respect of the signal, determining a measure of variation of the frequency offset measurements and eventually determining at least one of a charmel quality parameter and a speed parameter as a function of the measure of variation of the frequency offset measurements. A further embodiment comprises frequency offset measurements made in respect of the signal and used for adjustments to a frequency of a local frequency source to synchronize with a remote frequency source whereby those adjustments to the frequency are used as said frequency offset measurements.
