Patent ID: 8711974

Claim:
A non-linear amplifier system comprising: a reference output generator for receiving an input signal and generating a reference output; an adaptive filter for generating a modified input signal based on the input signal and the reference output; an amplitude distortion (AM-AM) compensator for acting on the modified input signal to compensate for AM-AM distortion; a phase distortion (AM-PM) compensator for acting on the modified input signal to compensate for AM-PM distortion; and an adaptive spectrum controller for providing parameters to the adaptive filter to minimize the power spectral density (PSD) of an output of the non-linear amplifier system in a stop-band and maximize the PSD of the output of the non-linear amplifier system in a pass-band; and a non-linear system for receiving at least one of the modified input signal and the compensated baseband signal and for generating the output of the non-linear system.
