Method and device for cancelling frequency offsets

摘要

A method and device for canceling frequency offsets in received modulated signals. The frequency offset cancellation device (17) includes a downconverter module (30), a channel unit (40) and a control module (50). The downconverter module (30) shifts received signals to a lower frequency. The channel unit (40) searches the shifted received signals and demodulates them, and the control module (50) adjusts the downconverter (30) in accordance with frequency offset information generated by the channel unit (40), thereby continuously cancelling out any frequency offsets that may have occurred during frequency shifting. <IMAGE>
