A radio channel estimation result which is an estimation result of a state of a propagation path to a mobile terminal that is a communication target, is generated. Whether a correction operation for correcting a frequency drift of a radio frequency used in radio communication between a radio base station and the mobile terminal has converged or not is determined. Then, a moving speed of the mobile terminal is estimated using only the radio channel estimation result at the time when the correction operation has converged. |
