GPS技术在PAS帧信号同步系统中的应用

GPS Technology and Its Application in Frame-signal Synchronization of PAS

从采用来自 GPS的精确 PPS信号来同步 RP子系统的思路出发 ,通过设计专用的 GSG模块和 GPS信号接收装置 ,实现了相距较远的 RPC帧信号同步 ,优化了频谱利用率 ,解决了现行系统中源自不同 RPC的 RP帧信号不同步和小功率基站之间的同步干扰问题 ,为小功率覆盖无盲区提供可靠的技术保障 ,是一种可行的解决 PA

This paper starts with adoption precision PPS signal based on GPS to synchronize RP subsystem, by designing special GSG module and GPS receiver realize RPC framesignal synchronization far away Optimizing the spectrum utilization efficiency We have resolved the RP framesignal nonsynchronization and synchronization interfere between lowpower from different RPC′s RP framesignal Providing a credible technique ensure with lowpower nonblindarea It is a feasible and virtual method to resolve PAS′s framesignal synchronization
