Abstract
A storage unit stores a first lookup table including a plurality of correction coefficients for I codes, and stores a second lookup table including a plurality of correction coefficients for Q codes. Each of the correction coefficients for I codes and each of the correction coefficients for Q codes are complex numbers. A distortion compensation unit compensates, with one of the plurality of correction coefficients for I codes, distortion of an I code of a transmission signal to generate a first input signal, outputs the first input signal to an SCPA for I codes. The distortion compensation unit compensates, with one of the plurality of correction coefficients for Q codes, distortion of a Q code of the transmission signal to generate a second input signal, and outputs the second input signal to an SCPA for Q codes.
