摘要：
A phase tracking circuit includes a divider part dividing an input signal that includes data sub-carriers and pilot sub-carriers into groups so that each of the groups includes at least one of the pilot sub-carriers, and a correcting part correcting phases of data sub-carriers of the input signal included in one of the groups on the basis of an amount of phase rotation of the at least one of the pilot sub-carriers included in the above one of the groups.
