Distortion cancellation using adaptive linearization

A method of signal processing, comprising:

• receiving a distorted signal comprising a distorted component and an undistorted component, wherein the distorted component is at least in part attributed to an exogenous signal, and the exogenous signal is a signal that is different from the distorted signal that is received;
• obtaining information associated with the exogenous signal;
• and
• performing linearization, based at least in part on the distorted signal and information associated with the exogenous signal, to obtain a corrected signal that is substantially similar to the undistorted component.

A computer program product for signal processing, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions stored therein for:

• receiving a distorted signal comprising a distorted component and an undistorted component, wherein the distorted component is at least in part attributed to an exogenous signal, and the exogenous signal is a signal that is different from the distorted signal that is received;
• obtaining information associated with the exogenous signal;
• and
• performing linearization, based at least in part on the distorted signal and information associated with the exogenous signal, to obtain a corrected signal that is substantially similar to the undistorted component.

A digital receiver system, comprising:

• an interface configured to receive an analog signal;
• a mixer configured to demodulate the analog signal to generate a demodulated signal;
• an analog to digital converter configured to convert the demodulated signal to a digital signal, the digital signal comprising a distorted component and an undistorted component, wherein the distorted component is at least in part attributed to an exogenous signal, and the exogenous signal is a signal that is different from the distorted signal that is received;
• and
• an adaptive distortion reduction module configured to:
• obtain information associated with the exogenous signal;
• and
• perform linearization, based at least in part on the digital signal and information associated with the exogenous signal, to obtain a corrected signal that is substantially similar to the undistorted component.
