1. A calibration method for calibrating an amplifier comprising:

  • decomposing the input signal into a channel pair by applying a nonlinear function to the input signal;

    modeling the amplifier to generate an estimated amplifier transfer function for each of N channels processing a decomposed version of an input signal; and

    computing equalizer values for equalizers that are applied to each of the N channels prior to amplification, wherein the computing of equalizer values are based on the estimated amplifier transfer function for each channel in conjunction with a plurality of error criteria combined with weighting from each of the plurality of error criteria.
