This gain control device (9) controls a gain of a received signal containing a predetermined pilot symbol for carrier synchronization. The gain control device (9) is equipped with: an extraction unit (91) for extracting the pilot symbol from the received signal; a pilot error calculation unit (92) for calculating an error between the pilot symbol extracted by the extraction unit (91) and an expected value for the pilot symbol; and a gain control unit (93) for correcting the gain of the received signal in accordance with the error calculated by the pilot error calculation unit (92). |
