Information handling system including adaptive interference suppression feature and method of operation

A method of operating an information handling system (IHS) including a wireless device that is coupled to the IHS, comprising:

• predetermining a corrective interference profile that comprises filter characteristics, wherein the predetermining comprises:
• measuring a first interference of a processor that is located in the IHS when the processor is operating in a first power mode, wherein first filter characteristics are determined using the first interference;
• and
• measuring a second interference of the processor that is located in the IHS when the processor is operating in a second power mode, wherein second filter characteristics are determined using the second interference;
• providing a wireless signal through the wireless device subsequent to the predetermining of the corrective interference profile;
• detecting when the processor changes mode of operation from the first power mode to the second power mode;
• filtering the wireless signal by an adaptive filter employing the first filter characteristics when the processor is operating in the first power mode, wherein the adaptive filter receives the wireless signal, modifies the wireless signal using the first filter characteristics to provide a modified wireless signal, and subtracts the modified wireless signal from the wireless signal to create a filtered signal;
• and
• filtering the wireless signals by the adaptive filter employing the second filter characteristics when the processor is operating in the second power mode, wherein the adaptive filter receives the wireless signal, modifies the wireless signal using the second filter characteristics to provide a modified wireless signal, and subtracts the modified wireless signal from the wireless signal to create a filtered signal.
