Abstract:
Systems and methods for mitigating intermodulation distortion in a receiver include receiving, at processing electronics, a radio frequency signal. An envelope of the received signal is detected to form a rectified envelope signal. A portion of the envelope signal attributable to intermodulation distortion may be isolated from the envelope signal. The isolated distortion may be used to reduce the gain of the received radio frequency signal.
