Synchronicity detection apparatus

摘要

In order 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 matched filters, a synchronicity detection device detects the timing of a prescribed spread code included in a reception signal. The device includes a correlation coefficient generation means (130) which divides and generates a replica code of a spread code of a prescribed length while the phase advances at each interval of a prescribed width. Matched filters (103,104) perform detection of correlation values of reception signals and replica codes are generated by the correlation coefficient generation means (130) at each interval of a prescribed width.
