<p>Method and device for, when receiving a radio signal from a moving transmitter (105), calculating the velocity of movement of the transmitter (105), using Rayleigh-fading of the received radio signal, comprising at least two parallel calculations of a value using the velocity of movement of the transmitter, and using the results of the calculations as basis for making a decision. Said decision is arranged to choose the value which is optimal for the velocity calculation.</p> |
