2.1. The invention relates to a receiver for time-varying distorted data signals, with an equaliser, a channel estimator which, with the aid of a training signal transmitted along with the data signals and a replica of the training signal stored in the receiver, generates a channel information signal which it feeds to the equaliser, and with an arrangement for channel tracking which, with the aid of data detected by the equaliser, generates correction values for the channel information signal. With very high relative speeds between the transmitter and the receiver (e.g. 200 km/h during operation of the mobile radio unit, for example in a vehicle), this can nevertheless result in a deterioration in the bit error rate. …<??>2.2. This is prevented in the case of the present invention by supplying to the channel tracking arrangement, following transfer of the channel information determined from the training signal, a part at least or all of the received training signal prior to the data signals which are to be equalised and detected. …<??>2.3. One application of the invention is in mobile radio units. …<IMAGE>… |
