A synchronization acquiring device and method for realizing synchronization acquisition at high speed equivalent to that of parallel search with a simple constitution similar to that of series search. A synchronization acquiring device (100) has a superposition template acquiring section (120) for acquiring superposition template signals generated by superposing template signals on one another, a first correlation detecting section (110) for detecting preliminary correlation matching between a superposition template signal and the received signal and, if the preliminary correlation matching is not detected, detects preliminary correlation matching after replacing the superposition template signal with another superposition template signal, and a second correlation detecting section (130) detects, if preliminary correlation matching is detected, the final correlation matching between a superposition template signal out of the template signals and the received signal.
