<p>Provided in the present invention is a synchronization searching method, which includes: calculating a hysteresis autocorrelation function of data sample points of a received signal; according to the hysteresis autocorrelation function, determining a time offset measurement of the data sample points; according to the time offset measurement, calculating estimated values and of a time offset and a frequency offset of the data sample points; according to the estimated value or, performing cross correlation using the received signal and a primary synchronization channel P-SCH, so as to acquire the beginning of a P-SCH symbol and the beginning of half-frame.</p> |
