Abstract： |
The present invention is one kind of fast reliable time interval synchronizing capture method in W-CDMA subzone search and time interval synchronizing device of the said method. From main synchronizing sequence matching result of matched filter, the device selects correlative peaks and correlative position exceeding certain threshold for record and analysis. When correlative peaks in required number repeatedly appear in some indentical position, the synchronizing sequence is judged to be captured, or else the threshold is regulated to next record and analysis course. In case of no synchronizing sequence is captured in specified time, the device exits from the capture course and some capture failure indication is given out. |
