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.

Abstract: Aspects relate to outputting a training field signal and/or obtaining a training field signal over multiple radio frequency (RF) sub-bands. For example, a carrier bandwidth used by a first apparatus to transmit packets may include several RF sub-bands. The first apparatus may use two or more of these RF sub-bands to transmit a training field signal. In some examples, the first apparatus may repeat the same training field signal over multiple RF sub-bands. In some examples, the second apparatus may combine the training field signal sent over the multiple RF sub-bands.
