CALIBRATION OF A SYNTHESISER IN A RADIO RECEIVER

A method of operating a radio receiver arranged to receive a plurality of data symbols transmitted on one of a predetermined set of frequencies. The method comprises receiving a first set of data symbols at a first transmission frequency. The first set of data symbols comprises a message indicating...

Zusammenfassung:	A method of operating a radio receiver arranged to receive a plurality of data symbols transmitted on one of a predetermined set of frequencies. The method comprises receiving a first set of data symbols at a first transmission frequency. The first set of data symbols comprises a message indicating a first frequency sub-set. A synthesiser is calibrated for the one or more frequencies in the first frequency sub-set. A second set of data symbols transmitted on at least one of said one or more frequencies from the first sub-set is received. It is determined from the second set of data symbols whether a network quality metric exceeds a threshold. The synthesiser is calibrated for one or more frequencies in a second frequency sub-set when the network quality metric exceeds the threshold. The second sub-set comprises frequencies that are not in the first sub-set.
