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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frequency switching within time domain digital pre-distortion","description":"Appropriate signal processing may be beneficial in a variety of communication systems and elements thereof.
