摘要
无线通信领域的发展离不开时钟同步关键技术,相较于传统的无线通信方式,5G通信技术对于系统的时钟同步提出了更严格的要求。针对同步以太网(SyncE)技术和IEEE1588V2精密时钟同步协议(PTP)进行了介绍,阐明了其对于5G技术发展的必要性,并基于上述技术设计了针对5G一体化基站的时钟同步系统,从技术方法、硬件设计、软件设计及系统实现等方面进行了详细介绍,通过搭建实验环境,在时钟同步精度和稳定性方面验证了系统的可行性。
The development of wireless communications cannot be separated from the key technology of clock synchronization. Compared to the traditional wireless communication methods, stricter requirements for clock synchronization of systems are put forward in 5G communication technology. The Synchronous Ethernet (SyncE) technology and IEEE 1588V2 Precision Clock Synchronization Protocol (PTP) are introduced, and their necessity for the development of 5G technology is clarified. Based on the above technologies, a clock synchronization system for integrated 5G base stations is designed. The technical methods, hardware design, software design, and system implementation are described in detail. Finally, an experimental environment is established, in which the feasibility is verified in terms of clock synchronization accuracy and stability.
