PROBLEM TO BE SOLVED: To precisely provide a phase correction value even when a phase error or noise level is large.SOLUTION: In a phase error correction section 9, a signal extraction section 90 extracts a received reference signal GI from received signals; and an error vector calculation section 91 calculates an error vector in a phase error by comparing with a known reference signal to be transmitted. A representative vector calculating section 92 classifies the error vectors into two or more groups based on the frequency and calculates a representative vector of each group. A correction value calculation section 93 calculates a phase correction value of each frequency based on plural representative vectors. A phase correction section 94 corrects phase error in each frequency by using the calculated phase correction value. |
