Localization is performed by finding outliers in ADC data [2]. Using the thresholds set from the interference statistics, these outliers can be found Samples that cross this threshold in energy can be marked as having been affected by interference. Note that options are available to use either the ‘absThreshold’ and/or the ‘absDiffThreshold’ to detect the outliers.

In the 2944, each sample is marked by an interference indicator bit (or IIB), which is zero if below threshold and 1 if it is above. This sequence can then be provided to a Hysteresis module which optionally provides hysteresis. Finally this IIB bitstream is send to the mitigation module, where it is used to identify interferer locations.
