ABSTRACT:
A frequency error occurring in a repeater station and a receiving side radio station 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. 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 and the downconverter of the receiving side can be eliminated effectively.
