摘要：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 iscompared with a reference value. When an upper-frequency distortion component of apilot signal is larger than the reference value, the gain and phase of a frequencycharacteristic compensator of the distortion generation path are controlled so that theupper-frequency distortion component of the pilot signal becomes smaller than a valuepreset in the controller. When a lower-frequency distortion component of the pilotsignal is larger than a reference value, the gain and phase of the frequency characteristiccompensator of the distortion generation path are controlled so that the lower-frequency distortion component of the pilot signal becomes smaller than a value presetin the controller.
