<P>PROBLEM TO BE SOLVED: To accurately correct a phase error even if it is large. Ž<P>SOLUTION: At a correction value calculation section 125, the phase error Δθ[t n] of each pilot carrier calculated by a phase error calculation section 124 is mapped onto a unit circle of an IQ plane. A vector representing each phase error Δθ[t n] is added on the IQ plane, and a phase represented by an vector of the addition results is obtained as a phase error correction value Θ [t]. The phases of all the data carriers are rotated by the same quantity as the phase represented by the phase error correction value Θ [t], thus correcting the phases by a correction section 126. The present invention can be applied to a receiving device for receiving an OFDM signal. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
