1. A method of narrowband interference detection and mitigation during reception of wireless signals, the method comprising:
receiving a wireless signal in an operating frequency band on a wireless communication medium by a wireless communication device;
observing a frequency domain representation of the wireless signal and measuring a plurality of power related values of the frequency domain representation;
identifying a maximum power value of the power related values and a sub-carrier associated with the maximum power value;
calculating a threshold power value based on the maximum power value and a scale factor;
counting a number of sub-carriers having power related values below the threshold power value;
determining whether narrowband interference is present based on the counted number of sub-carriers; and
in response to the presence of narrowband interference in the operating frequency band, determining one or more sub-carriers affected by narrowband interference and modifying the wireless signal based on the determined sub-carriers affected by narrowband interference.
