Claim Text:
1. A compensation apparatus configured to perform a compensation process of removing an image component in a quadrature-demodulated signal, the compensation apparatus including a quadrature demodulation compensation section configured to compensate for the quadrature-demodulated signal including an I signal and a Q signal, wherein the quadrature demodulation compensation section comprises: an image component rejection section that removes a first image component caused by a quadrature demodulator that outputs the quadrature-demodulated signal, and an equalizer for delay compensation that removes a second image component caused by a characteristic difference between frequency characteristic of a first filter that performs filtering of the I signal and frequency characteristic of a second filter that performs filtering of the Q signal, the second image component being a component that is not removable by the image component rejection section.
