Non-linear distortion compensating apparatus

摘要

When a distortion is compensated by a predistorter method, a distortion can satisfactorily be compensated by a simple arrangement. A limit operation can be made in such a manner that when a generated predistortion signal is held at a value smaller than a first level, this predistortion signal is not added to an input signal and that when a generated predistortion signal is held at a value larger than a second level which is larger than the first level, this predistortion signal is added to an input signal as a predetermined fixed value.
