Patent ID: 7760831

Claim:
An information handling system (IHS) including: means for predetermining a corrective interference profile that comprises filter characteristics in the IHS: a processor mounted in the IHS; a wireless device coupled to the processor and the IHS wherein wireless signals are provided through the wireless device subsequent to the means for predetermining a corrective interference; a controller, coupled to the processor and the IHS, operable to determine when the processor changes from a first power mode to a second power mode, wherein, a first interference of the processor being measured when the processor is operating in the first power mode; a second interference of the processor being measured when the processor is operating in the second power mode; first filter coefficients being determined from the first interference; second filter coefficients being determined from the second interference; and an adaptive filter, coupled to the wireless device, operable to employ the first filter coefficients when the processor is operating in the first power mode and to employ the second filter coefficients when the processor is operating in the second power mode, wherein the adaptive filter is operable to receive an original signal, modify that original signal using one of the first filter coefficients and the second filter coefficients to provide a modified signal, and subtract the modified signal from the original signal to create a filtered signal.
