摘要
A method and apparatus for controlling a feed-forward compensated power amplifier system employing a spread spectrum technique that includes a control signal or signals and injects a synthesized signal at an appropriate point within the feed-forward amplifier system to reduce distortion is described . The amount of bandwidth spread is controlled by the amount of processing gain required for the re-mapping process and the time response of the required system. The control signals after the re-mapping of the spread spectrum at the output of the system are correlated in the matched filter correlator and the result is used to control the injection of the extracted distortions into the reverse phase of the feed-forward amplifier output in polar or Cartesian coordinates.
