Method and apparatus for mitigating signal interference in a feedback system

A device, comprising:

• a memory to store instructions;
• and
• a processor in communication with the memory, wherein responsive to executing the instructions, the processor performs operations comprising:
• measuring, over a plurality of cycle times, power levels associated with frequency segments over a first radio frequency spectrum of a first wireless communication system;
• generating average power levels for the frequency segments from the power levels that are measured;
• eliminating a highest average power level from the average power level to generate a baseline average power level for the frequency segments;
• determining a threshold from the baseline average power level for detecting signal interference in the frequency segments of the first radio frequency spectrum of the first wireless communication system;
• determining a filter state to mitigate the signal interference, wherein the filter state is determined based on the signal interference that is detected via the threshold;
• adjusting a filter according to the filter state, wherein the filter is provided between an input terminal and a demodulator to filter an information bearing signal comprising a modulated carrier received at the input terminal, resulting in a filtered signal;
• receiving a first error signal indicative of errors corrected within information obtained by demodulation of the modulated carrier of the filtered signal;
• determining a modified filter state in response to the first error signal;
• and
• adjusting the filter according to the modified filter state.
