Abstract
A method and system for correcting errors introduced by a non-linear amplifying device to an input signal inputted to the device. A Look-Up Table (LUT) stores error correction values indexed against input signal amplitude values and input signal frequency values. The amplitude and frequency of an input signal to be inputted to the non-linear amplifying device are measured, and stored error correction values corresponding to the measured amplitude and frequency are retrieved from the LUT and used to modify the input signal accordingly.
