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.
Claims20
A method of mitigating intermodulation distortion in a receiver comprising:
- receiving, at processing electronics, a radio frequency signal;
- rectifying, by the processing electronics, the received signal to form an envelope signal and distortion components;
- isolating, by the processing electronics, the distortion components attributable to intermodulation distortion;
- and
- using the isolated distortion components to reduce the gain of the received signal.
A system for mitigating intermodulation distortion in a receiver comprising processing electronics configured to receive a radio frequency signal, wherein the processing electronics are configured to rectify the received signal to form a rectified envelope signal and distortion components, wherein the processing electronics are configured to isolate the distortion components attributable to intermodulation distortion, and wherein the processing electronics are configured to use the isolated distortion components to reduce the gain of the received signal.
A non-transitory computer-readable storage medium having instructions stored therein, the instructions being executable by a processor to cause the processor to perform operations comprising:
- receiving a radio frequency signal;
- rectifying the radio frequency signal to form a rectified envelope signal and distortion components;
- isolating the distortion components attributable to intermodulation distortion;
- and
- using the isolated distortion components to reduce the gain of the radio frequency signal.
