ABSTRACT:
A gain adjuster and a phase adjuster of a distortion generation path are set so that an extracted distortion component becomes small, the extracted component is compared with a reference value. When an upper-frequency distortion component of a pilot signal is larger than the reference value, the gain and phase of a frequency characteristic compensator of the distortion generation path are controlled so that the upper-frequency distortion component of the pilot signal becomes smaller than a value preset in the controller. When a lower-frequency distortion component of the pilot signal is larger than a reference value, the gain and phase of the frequency characteristic compensator of the distortion generation path are controlled so that the lower-frequency distortion component of the pilot signal becomes smaller than a value preset in the controller.
