摘要:A detected signal (111) contains a preamble portion which includes symbolalternations, followed by a unique word portion, and a data portion. Each time a symbolalternation is detected, a correction value calculation section (102) averages the phaseshift in the detected signal (111) for a predetermined length, thereby calculating acorrection value (115). The correction value determination section (103) stores a pluralityof correction values (115) in a chronological order. When the unique word portion isdetected, the correction value determination section (103) retains, as an effectivecorrection value (118), a correction value which is arrived at by going back a
predetermined number of correction values among the stored correction values. A phaserotation section (104) corrects the phase of the detected signal (111) by using aneffective correction value (118) calculated by the correction value determination section(103).
