Distortion compensating apparatus and method

摘要

The present apparatus includes: distortion amount detector (291) which detects the amount of distortion of an output signal of the amplifier (18); parameter holder (14 and/or 23); parameter corrector (292) which corrects a parameter held in the parameter holder (14 and/or 23) in such a manner that the distortion amount detected by the distortion amount detector (291) is improved; controller (293) which controls frequency components to be subjected to distortion amount detection that is performed by the distortion amount detector (291), based on the distortion amounts of a plurality of different frequency components of the output signal of the amplifier (18) and on specification values relating to the distortion amounts.
