FREQUENCY SWITCHING WITHIN TIME DOMAIN DIGITAL PRE-DISTORTION

Appropriate signal processing may be beneficial in a variety of communication systems and elements thereof For example, time domain digital pre-distortion may benefit from suitable treatment of frequency switching. A method can include determining whether an instantaneous frequency of an input signal is positive or negative. The method can also include selecting a pre-distortion model from a set of pre-distortion models based on the determination of positive or negative instantaneous frequency. The method can further include applying the selected pre-distortion model to the input signal for a time corresponding to the determination of instantaneous frequency to provide an output signal. The method can additionally include providing the output signal to a power amplifier.
