A distortion compensation unit (10) acquires, on the basis of both an analog signal being an output signal obtained from a 1-bit pulse train outputted by a DSM (6) and an IQ signal being an input signal to be inputted to the DSM (6), the asymmetric components of the 1-bit pulse train, and performs a distortion compensation on the basis of the asymmetric components. The distortion compensation unit (10) is caused to store asymmetric component data indicating the acquired asymmetric components. When the distortion compensation unit (10) acquires the asymmetric components, the distortion compensation unit (10) acquires, as the asymmetric components, the difference between an output baseband signal obtained by performing an orthogonal demodulation of the analog signal being the output signal and an input baseband signal appearing before an orthogonal modulation. |
