  • System and method for mitigating broadband interference
    Patent number: 11018783
    Abstract: Systems and methods for operating a communication device so as to mitigate intermodulation interference to a signal. The methods comprise: continuously monitoring several communication channels by the communication device; using a noise floor level estimate of the communication device to detect when the communication device is under an influence of hig interference; determining an optimal level of attenuation to be applied by a variable attenuator of the communication device's receiver so as to mitigate the influence of intermodulation interference to the signal; and selectively adjusting an amount of attenuation being applied by the variable attenuator to achieve the optimal level of attenuation for mitigating intermodulation interference.
    Type: Grant
    Filed: July 12, 2019
    Date of Patent: May 25, 2021
    Assignee: EAGLE TECHNOLOGY, LLC
    Inventors: Mac L. Hartless, Daniel W. Ericson, Nathan T. Prosser, Catherine D. Royster, Dennis Layne
  • System and method for optimizing intermodulation performance of receivers
    Patent number: 10931321
    Abstract: Systems and methods for mitigating broadband and/or Intermodulation (“IM”) interference. The methods comprise: monitoring performance of at least one demodulator performance metric of a communication device; detecting when the communication device is under or will be under an influence of IM interference based on a performance of the at least one demodulator performance metric; determining an improved level of gain to be applied to (i) a variable attenuator of the communication device or (ii) a variable gain low noise amplifier of the communication device; and selectively adjusting an amount of gain being applied by the variable attenuator or variable gain low noise amplifier based on the improved performance achieved with new level of attenuation.
