Abstract
A method for pre-processing a signal prior to receipt of the signal by a non-linear device (NLD) to compensate for AM-AM distortion and AM-PM distortion of the signal by the NLD. The method includes generating a modified amplitude rbased on an amplitude xderived from a digitized envelope Rof the signal, generating a scale factor cbased on the modified amplitude rand the amplitude x, generating an AM-AM compensated signal based on the scale factor c, generating a first AM-PM phase compensation value based on the modified amplitude r, and generating an AM-AM and AM-PM compensated signal by modifying a phase of the AM-AM compensated signal based on the first AM-PM phase compensation value.
