Zusammenfassung:A receiver 200 as a component in a wireless communication device 100 and a corresponding method are used for receiving a multi-carrier communication signal and determining a timing offset thereof. The receiver 200 comprises a controller 222 to perform a correlation on each of a plurality of sub-carriers comprising the multi-carrier signal to provide a plurality of timing offsets. A quality metric corresponding to each of the plurality of timing offsets may be employed to select the best timing offset. Alternatively, a set of timing offsets whose quality metric exceed a threshold may be averaged. Either the best or average timing offset is used for processing all the sub-carriers of the multi-carrier signal.
