摘要：
A frequency control device receiving a signal transmitted from each of a plurality of mobile stations, the frequency control device includes a first detecting unit to detect a frequency deviation generated from the signal, a second detecting unit to acquire information about at least a current position or movement of each of the mobile stations as classification information, and a classifying unit to classify mobile stations estimated to be moving in a same moving direction with a same moving speed as a first mobile station based on the classification information. The frequency control device includes a first calculating unit to calculate a first frequency deviations of a signal received from the first mobile station, and a compensation unit to compensate the frequency deviation of the signal received from the first mobile station based on the first frequency deviation.
