摘要 针对移动通信网络基站间需要建立高精度时间同步的需求,设计并实现了一种基于FPGA(field programmable gate array)与ARM(advanced RISC machines)的高精度时间同步器,并以3台时间同步器互相对比进行测试,功能实现较好。 Aim at the need of high precision time synchronization among the base stations of mobile communication network,a high precision time-synchronization device based on FPGA and ARM is designed.Three time synchronizers are tested and compared with each other,all the functions are well realized.
