A method is provided for extending dynamic range of a receiver. The method includes receiving a known input signal at the receiver, detecting a first output signal in response to the known input signal, and determining a correction function based on the first output signal and the known input signal for compensating for non-linear distortion introduced by the receiver. The method further includes receiving an unknown input signal at the receiver, detecting a second output signal in response to the unknown input signal, and applying the correction function to the second output signal in a time domain to recover the unknown input signal.
