Abstract
To be able to detect a plurality of correlations in a spread code cycle when receiving CDMA type signals spread with a prescribed spread code and performing correlation detections using a matched filters. A synchronicity detection device which detects a timing of a prescribed spread code already known included in a reception signal is equipped with a correlation coefficient generation meanswhich divides and generates a replica code of a spread code of a prescribed length while a phase advances at each interval of a prescribed width and matched filtersandwhich perform detection of correlation values of reception signals and replica codes generated by the correlation coefficient generation means at each interval of a prescribed width.
