Patent ID: 6928274

Claim:
A receiver device for a mobile radiocommunication unit communicating with a base station via a propagation channel comprising a pathfinder for determining time-delays associated with multipath signals applied to the pathfinder's input, said multipath signals being also applied to a first input of a combiner circuit and to a first input of a channel estimator, the output of said pathfinder being connected to a second input of said combiner circuit and to a second input of said channel estimator, which channel estimator provides an estimate of said propagation channel to a first input of a filter unit, adapted to provide an optimum estimate of said propagation channel to a third input of said combiner circuit as a function of a speed of the mobile radiocommunication unit, wherein said receiver device further includes a speed estimator for estimating the speed of said mobile radiocommunication unit, the input of said speed estimator being connected to the output of said channel estimator and the output of said speed estimator being connected to a second input of said filter unit, thereby supplying to it the estimated speed of said mobile radiocommunication unit in order to select the appropriate Wiener filter corresponding to the estimated speed.
