It relates to an adaptive noise canceling apparatus, the feedback signal of the high power amplifier to reduce the effect of noise components and improve the performance of the predistorter, even if the feedback signal is not good due to the influence of noise increases the feedback signal quality, additional distortion It provides an adaptive noise reduction apparatus and method for obtaining a compensation gain predistortion. Adaptive noise reduction apparatus predistortion converted distortion signal inverse predistortion output from the exchanger to the first feedback inverse predistortion to generate a signal portion, the first feedback signal and the second feedback output from the high-power amplifier for predistortion noise estimator for estimating noise by comparing the signal and the second feedback signal and the estimated adapted to remove noise enemy processing and the inverse predistortion based on a second feedback signal in the noise removal unit look-up table in (LUT ) includes an update to the adaptive update.
