ObjectTo reduce deterioration of transmission quality under circumstances where the moving speed is high.Overcoming MeansAn adaptive modulation control apparatus for adaptively selecting a modulation parameter from among a plurality of modulation parameters determined based on a plurality of modulation schemes, coding rates of error correction or a combination thereof corresponding to a propagation path state is provided with a reception state measuring section (2) that measures a reception state of a signal received from a communicating apparatus, a correcting section (3) that makes a correction to change propagation path information indicative of a measurement result of the propagation path state based on the measured reception state, and a modulation parameter selecting section (4) that selects a modulation parameter corresponding to the corrected propagation path information.
