Predistortion Techniques for Nonlinear Distortion Mitigation
Predistortion techniques attempt to compensate for non-linear distortions by modifying the input signal characteristics. These modifications can be either non-adaptive or adaptive. The most common non-adaptive technique studied in the literature and used in practice is amplitude clipping. Amplitude clipping limits the peak envelope of the input signal to a predetermined value, or otherwise passes the input signal through unperturbed, i.e.,
Equation 5.5
The distortions caused by amplitude clipping can be view as another noise source. Furthermore, the resulting noise caused by clipping ...
