The transceiver includes a modulator for modulating a data signal onto one or more carrier signals to generate a modulated signal and a power amplifier for amplifying the modulated signal. The transceiver also includes a data pre-distorter (DPD) for pre-distorting the data signal using a look-up table that represents a non-linear transfer function that is an inverse of the non-linear transfer function of the power amplifier. The DPD selects one or more look-up tables based on a feedback signal corresponding to a power level and/or a phase of the output of the power amplifier. The transmitter also includes a controller for comparing the output of the power amplifier to a desired output level and upon sensing changes, altering the amplitude and phase of the feedback signal to substantially constant values."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Digital pre-distortion linearization for mobile communication","description":"This disclosure provides systems, methods, and apparatus for a radio frequency transceiver.
