<p>A frequency error occurring in a repeater station (5) and a receiving side radio station (4, 6-8) is determined by using a dummy signal received from the repeater station, and is stored as frequency control data corresponding to the frequency error into a memory (209). By controlling a reception frequency based on the stored frequency control data, a data signal received from the repeater station is compensated for the frequency error. A relatively large frequency error such as the common frequency error occurring in the satellite (5) and the downconverter (7) of the receiving side can be eliminated effectively. <IMAGE></p> |
