Abstract:
1. A linearization system for training a linearization error compensation model comprising: (a) a tone generator for providing at least two different RF tones; (b) receiver path components for processing the RF tones; (c) an analog-to-digital converter for converting the processed RF tones into digital signals; and (d) a processor for using the digital signals to train the linearization error compensation model in advance of operational use, wherein the processor is configured for training the linearization error compensation model by using spectral locations of intermodulation distortion products from the digital signals and wherein using the spectral locations of the intermodulation distortion products comprises extracting magnitudes and phase values for each distortion product, transforming the magnitudes and the phase values into the time domain, and inserting the transformed magnitudes and the transformed phase values into the linearization error compensation model.
