Abstract: A communication synchronization apparatus with which a station detects, for each slot in a predetermined unit, a correlation value between an input signal and a spreading code generated by the station itself, the detection process for the correlation value is performed over several slots, the correlation values obtained in the slots are integrated to detect a correlation peak value, and thereby a synchronization point of said input signal is detected, said apparatus comprising a controlling section for ending the integration when the number of paths, at which a power integration value for converting the detected correlation value into a power value has reached a reference set value, reaches a path count set value.
