  • Signal processing
    Publication number: 20040240584
    Abstract: The input signal to a digital predistorter (14) is interpolated (28) and frequency converted (36 to 44) to condition it for predistortion. Similar conditioning can be applied to signals in a feed-forward lineariser.
    Type: Application

  • Signal correction techniques
    Publication number: 20040232984
    Abstract: Errors present in the output of an amplifier (10) are compared with the amplifier input in a control unit (24) to derive corrected coefficients for a look-up table used by predistorter (12) to eliminate distortion in the output of the amplifier (10). Depending on the format of the predistorter (12), at least some of the coefficients are corrected using measured errors that have been rendered independent of the input signal's amplitude.
