An amplifier apparatus for providing a pre-distortion to perform a distortion compensation, wherein even if the frequency of occurrence of levels around the input signal peak is small, a distortion compensation table is efficiently updated so as to improve the performance of the distortion compensation. The compensation values of a distortion compensation table () are divided into a first group of compensation values corresponding to large input levels that lead to large output distortions and a second group of compensation values corresponding to the other small input levels. If a level detected by a level detecting part () exceeds a threshold value, a control part () updates the first group of compensation values. Otherwise, the control part () updates the second group of compensation values. In this way, the updating process can be effectively performed even for signals having small frequencies of occurrence of the peak values of the signal levels as in the CDMA or OFDM system, thereby improving the performance of the distortion compensation.
