AMPLITUDE/ORTHOGONALITY ERROR COMPENSATION DEVICE

摘要

In order to more accurately correct the amplitude and the orthogonality when multiple signals of different frequencies are included in an input signal, an amplitude/orthogonality error compensation device (100) has: an amplitude correction unit (10) that performs amplitude correction with respect to the in-phase component and the orthogonal component of an input complex signal on the basis of amplitude error information, and outputs the obtained amplitude-corrected complex signal; an orthogonality correction unit (20) that performs orthogonality correction with respect to the amplitude-corrected complex signal on the basis of orthogonality error information, and outputs the obtained orthogonality-corrected complex signal; a filter unit (30) that transmits a prescribed frequency component of the orthogonality-corrected complex signal; an amplitude error detection unit (40) that obtains amplitude error information on the basis of the in-phase component and the orthogonal component of the complex signal that has passed through the filter unit (30); and an orthogonality error detection unit (50) that obtains orthogonality error information indicating the orthogonality error between the in-phase component and the orthogonal component of the complex signal that has passed through the filter unit (30).
