Abstract text

A method of predistorting a waveform for input to an amplifier includes receiving information associated with the waveform, the information comprising a modulation configuration of the waveform. The method further includes predicting a chain model for the waveform based on the modulation configuration. In addition, the method includes predistorting the waveform for input to the amplifier, based on the chain model, an ideal waveform, and target output power. An apparatus is also provided for predistorting a waveform for input to an amplifier.
