Abstract
A method and device for processing spur components associated with a received wireless signal are disclosed. In one embodiment, the method includes first selecting a sub-band of a spectral band of the received signal. The selected sub-band is scanned, and a detection routine is executed to detect a spur within the scanned sub-band having a peak magnitude above a predetermined threshold. The spur frequency is determined, and the spur may be removed by a cancellation unit based on the determined frequency. The method also includes tracking the frequency of the spur to ensure continued suppression over time and under dynamic conditions.
