CDMA基站子系统同步原理和实现技术

The Synchronization Principle and Realization Technique of Base Station Subsystem in CDMA

讨论了CDMA数字PLMN网与PSTN之间主从同步运行方式和准同步运行方式的原理和实现技术.指出采用准同步运行方式,可以合理地协调与BSS相关的两套时钟基准;无代价获得GPS高质量的时钟实现传输同步;简化了CDMA基站同步系统设计.

By discussing and comparing the principle and realization technology for two synchronous method (masterslave synchronous and pseudosynchronous) between CDMA digital PLMN and PSTN, it makes a conclusion that by adopting high quality reference clock from GPS, pseudosynchronous method can coordinate the two reference clocks of BSS and realize transport synchronization without adding any cost. This method can simplify BSS design.
