Abstract
A method and apparatus for estimating the speed of relative movement of a transmitter and a receiver which are in communication with each other in a telecommunications system. The transmitter and receiver are in communication via a channel of the telecommunications system by a carrier wave. An analysis is made of the variations of amplitude or power of the signal transmitted by the transmitter and the channel between the transmitter and the receiver. The dopler shift undergone by the carrier wave is deduced from the variations, and the speed of movement is thereby deduced.
