Abstract
A distortion compensator that compensates for nonlinear distortion of an amplifier that amplifies power of a multicarrier signal includes a first compensation unit that performs first distortion compensation to collectively compensate for first nonlinear distortion that occurs in contact with a carrier frequency of the multicarrier signal, and second nonlinear distortion that occurs at a frequency at a predetermined distance from the carrier frequency, and a second compensation unit that performs second distortion compensation to compensate for only the first nonlinear distortion, of the first nonlinear distortion and the second nonlinear distortion.
