ABSTRACT:
A detected signal111contains a preamble portion which includes symbol alternations, followed by a unique word portion, and a data portion. Each time a symbol alternation is detected, a correction value calculation section102averages the phase shift in the detected signal111for a predetermined length, thereby calculating a correction value115. The correction value determination section103stores a plurality of correction values115in a chronological order. When the unique word portion is detected, the correction value determination section103retains, as an effective correction value118, a correction value which is arrived at by going back a predetermined number of correction values among the stored correction values. A phase rotation section104corrects the phase of the detected signal111by using an effective correction value118calculated by the correction value determination section103.
