Null interface synchronization method and base station

摘要: The embodiment of the invention relates to wireless communication technology, in particular a null interface synchronization method and base station, which are used for solving problem that stability station is influenced due interference global positioning system (GPS) GPS-based mode prior art. provided by comprises following steps that: detects downlink pilot time slot (DwPTS) reference corresponding by, determines synchronous code (SYNC-DL) from signal detected DwPTS; basic midamble performs channel estimation using according SYNC_DL acquire information; performed frame number (SFN) determined reading broadcast information acquired information. network can perform without GPS or with unstable adopting invention, so normal operation guaranteed.
