<p>The present invention has disclosed a synchronization capture method of downline in CDMA system and broadcast channel receiver for carrying out the method. Include: add broadcast channel to the downline, and put unique cord in the fixing slot of broadcast channel frame; first, broadcast channel receivers of mobile station find out the position of energy concentration on which main peak of each symbol occurs, then according to the position determine the time at which each symbol is decided, and making symbol decision; second, detecting the unique cord by the unique cord match filter, if the unique cord is detected, then giving synchronization information. The present invention uses broadcast channel, match filter structure and sliding relative technique to implement the fast sync receive of downline, and have high accuracy of synchronization. The method is simple and easy to carry out.</p> |
