Technique for Extremely High Order IM Correction

摘要

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.

1. A method comprising:
creating a modified input signal by increasing at least one portion of an input signal, where each of the at least one portion of the input signal comprises at least one high order intermodulation product; creating a pre-distorted signal by pre-distorting the modified input signal in accordance with a finite signal plan; and creating an output signal by amplifying the pre-distorted signal.
