摘要： A system is provided for pre-distorting a transmit signal in a mobile terminal prior to amplification by a power amplifier to compensate for AM to AM and AM to PM distortion over an input value range. Pre-distortion circuitry includes both amplitude and phase pre-distortion circuitries. The amplitude pre-distortion circuitry distorts an amplitude component of a polar transmit signal using an amplitude compensation signal that essentially cancels the AM to AM distortion, and the phase pre-distortion circuitry distorts a phase component of the polar transmit signal using a phase compensation signal that essentially cancels the AM to PM distortion. The amplitude and phase compensation signals are generated based on corresponding sets of coefficients selected from a number of sets of coefficients defining polynomials describing compensation signals for each of at least two subsets of the input value range for each of two or more power levels of the power amplifier circuitry.

摘要： Printers and methods for operating a printer are provided. One method comprises receiving a print order associated with image data for use in printing a plurality images; converting the image data into actions to print the plurality of images on a receiver medium with print adjacent areas between the printed images, the converting being performed in accordance with printer settings; printing a first set of color patches in the print adjacent areas when the each of the first set of calibration color patches can be printed in the print adjacent areas; printing a second set of color patches in the print adjacent areas when each of the first set of color patches cannot be printed in the print adjacent areas; and sensing the color of each printed color patch and recalibrating the printer settings based upon the sensed colors.

摘要： A printer and method for operating a printer are provided that prints using a receiver medium having a rolled portion with an outermost layer from which an unrolled portion extends to a print engine. The method comprises: sensing a condition indicating the receiver medium may have been contacted by other than a component of the printer or by a donor material applied by the print engine; measuring an aspect of the receiver medium indicative of the circumferential length of the outermost layer; determining a circumferential length of the receiver medium based upon the measured aspect of the rolled portion of the receiver medium; determining an exclusion length of the receiver medium based upon the determined circumferential length and a travel distance that is a representation of a length of the unrolled portion between the rolled portion and the print engine; and automatically advancing the receiver medium by the exclusion length.
