METHODS AND DEVICES FOR PREDISTORTION OF SIGNALS

A method (100) for predistorting an input signal (322, 422, 522) of an amplifier device (331, 500, 660) comprises evaluating (110) a selection criterion for a computational model of the amplifier device (331, 500, 660). The computational model provides an output signal (326, 526) of the amplifier de...

Zusammenfassung:A method (100) for predistorting an input signal (322, 422, 522) of an amplifier device (331, 500, 660) comprises evaluating (110) a selection criterion for a computational model of the amplifier device (331, 500, 660). The computational model provides an output signal (326, 526) of the amplifier device (331, 500, 660) for the input signal (322, 422, 522) of the amplifier device (331, 500, 660). Further, the method (100) comprises selecting (120) between a first computational model of the amplifier device (331, 500, 660) and a second computational model of the amplifier device (331, 500, 660) based on the evaluated selection criterion. Additionally, the method (100) comprises predistorting (130) the input signal (322, 422, 522) of the amplifier device (331, 500, 660) using the selected computational model.
