Abstract: A method for correcting high order IM products is described. The method includes creating a modified input signal by increasing one or more portions of an input signal (such as the whole time domain signal for example). The input signal consists of a desired signal and other non-linear products. Each of the one or more portions includes high order IM products. A pre-distorted signal is created by pre-distorting the modified input signal in accordance with a finite signal plan. An output signal is generated by amplifying the pre-distorted signal. Apparatus and computer-readable media are also described.
