description An amplitude/orthogonality error compensator includes: an amplitude corrector configured to perform an amplitude correction on an in-phase component and a quadrature component of an input complex signal based on amplitude error information, and to output a complex signal obtained through the amplitude correction; an orthogonality corrector configured to perform an orthogonality correction on the complex signal, obtained through the amplitude correction, based on orthogonality error information, and to output a complex signal obtained through the orthogonality correction; a filter section configured to allow a predetermined frequency component included in the complex signal obtained through the orthogonality correction to pass through the filter section; an amplitude error detector configured to obtain the amplitude error information based on the complex signal that has passed through the filter section; and an orthogonality error detector configured to obtain the orthogonality error information of the complex signal.
