1. A system for digital correction for a dynamically varying non-linear system, comprising:
a correction circuitry including at least one look-up table (LUT), wherein the correction circuitry is configured to receive an input signal and modify the input signal to be processed by the non-linear system using at least one LUT to correct non-linearity incurred by the non-linear system, wherein the at least one LUT is addressed by a magnitude or power of the input signal and a dynamically varying parameter associated with the input signal,
wherein the dynamically varying parameter is one of average signal power of the input signal, a differential of the average power of the input signal, a directional beam index, or temperature.
