<p>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 rk based on an amplitude xk derived from a digitized envelope Ri;k of the signal, generating a scale factor ck based on the modified amplitude rk and the amplitude Xk, generating an AM-AM compensated signal based on the scale factor ck, generating a first AM-PM phase compensation value based on the modified amplitude rk, 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.</p> |
