It relates to a distortion compensation device, to an apparatus and method for compensating for nonlinear distortion and linear distortion characteristics of the channel filter characteristics of the high power amplifier. Automatic distortion compensating apparatus adapted linear distortion estimating the adaptive linear distortion of the downlink signal the frequency is down on the basis of the linear distortion compensation signal output from the output in the high output amplifier frequency is complex and a down-down-signal pre-equalizer and an adaptive estimating part for estimating a non-linear distortion estimate the nonlinear distortion of the estimated linear distortion signal and the estimated linear distortion signal is adaptively on the basis of the non-linear distortion compensation signal output from the predistorter.
