Claim of US Patent No. 10,798,718

1. A method, comprising:receiving, by a processing system comprising a processor, interference information associated with a plurality of communication devices, the interference information determined from signal interference detected in a plurality of radio frequency signals wirelessly received at the plurality of communication devices, wherein the radio frequency signals comprise a direct sequence spread spectrum (DSSS) signal, and;
detecting, by the processing system, a first interferer of a plurality of interferers based on a comparison with an adaptive threshold value, wherein the detecting further comprises:
determining a number of sequences of the DSSS signal included in a rolling average to determine a subchannel having an interference;
selecting a predetermined number of subchannels, as selected subchannels, having a highest average signal strength over the number of sequences;
determining a baseline average signal strength across a spectrum of subchannels of the DSSS signal over the number of sequences without the selected subchannels;
calculating the adaptive threshold value from the baseline average signal strength; and
comparing a signal strength of a subchannel over the number of sequences with the adaptive threshold value to determine the first interferer in the subchannel; and
identifying, by the processing system, a source interferer for the first interferer by comparing characteristics of the first interferer with profile characteristics indicated in a profile for the source interferer, wherein the profile is stored in a database of profiles of interferers, and wherein the comparing is based on determining a measure of similarity between the characteristics and the profile characteristics.
