Application of GPS technology in frame-signal synchronization system of wireless broadband access

On the basis of adoption precision PPS signal from GPS to synchronize RP subsystem, this article realizes RPC frame-signal synchronization far away by designing Specific GSG module and GPS receiver, which can Optimize the spectrum utilization efficiency. The non-synchronization of RP frame-signal from different RPC and synchronization interference from different low-power base station have been resolved. Reliable technical support can be provided for low-power non-blind-area. It is a feasible and effective method to resolve frame-signal synchronization of wireless broadband access System.
