The present invention provides a method of estimating a frequency offset. The method comprises receiving a wireless signal timed according to a first frequency; generating a local signal timed according to a second frequency; and performing a plurality of synchronisation searches, each search comprising obtaining a set of correlation results indicative of a correlation between the wireless signal and the local signal at different timing offsets of the wireless signal relative to the local signal. The method then comprises finding a series of results, with a result from each of a plurality of the synchronisation searches, for which the difference in timing offset between results from adjacent searches in the series is within a maximum specified value. A frequency offset between the first and second frequencies can be determined from the series. |
