1. A device, comprising:

  • a processing system including a processor; and

    a memory that stores executable instructions that, when executed by the processing system,facilitate performance of operations, comprising;

    receiving a first Direct Sequence Spread Spectrum (DSSS) signal within a radio frequency spectrum;

    obtaining a signal strength for each of a plurality of channels within the first DSSS signal resulting in a plurality of signal strengths;

    sorting the plurality of signal strengths of the plurality of channels according to signal strength;

    selecting a first portion of the plurality of signal strengths and a second portion of the plurality of signal strengths, wherein each of the signal strengths of the first portion has a higher value than each of the signal strengths of the second portion;

    determining that one or more of the signal strengths of the first portion of the plurality of signal strengths includes an interference signal resulting in a group of interference signals,generating tuning coefficient data to suppress at least a portion of the group of interference signals while engaged in a communication session;

    receiving a second DSSS signal within the radio frequency spectrum; and

    filtering the second DSSS signal according to the tuning coefficient data to filter the portion of the group of interference signals using a filter, wherein the filter is a combination of notch filters, and wherein each notch frequency of the notch filters corresponds to a frequency of one of the group of interference signals.
