Abstract
Methods and devices for narrowband interference detection and mitigation during reception of wireless signals. Exemplary interference detection methods or devices observe a frequency domain representation of a received wireless signal to measure power related values, identify a maximum power value and an associated sub-carrier, count sub-carriers having power related values below a threshold power value, detect and locate narrowband interference based on the counted number of sub-carriers. Accordingly, exemplary interference mitigation methods or devices modify the wireless signal based on sub-carriers determined to be affected by narrowband interference in a time domain, frequency domain, or both time and frequency domains. An embodiment of the method or device processes the wireless signal to suppress frequencies associated with the narrowband interference locations by one or more notch filters in the time domain, the device then modifies power related values associated with the sub-carrier affected by narrowband interference in the frequency domain.
