摘　　要：为了满足某战术通信系统终端IP化接入的发展要求,提出了一种基于FPGA的Eo PDH(Ethernet over PDH)传输系统;该系统采用逻辑编程的方式实现接口协议、数据格式转换等主要处理环节,融合既有功能组件实现话音业务的传输、链路的管理控制等功能;仿真和试验表明,系统的处理核心可以线速处理数据业务,处理延时相对固定可控,支持用户直接通过以太网口进行数据业务的透明传输,支持数话同传,与既有的通信系统融合度高。An Ethernet over PDH transmission system based on FPGA is established, to meet the requirement of the IP-based tactical communication terminal. The system implement the main processing parts such as interface specifications and data format conversion by logic programming method, and combine with the present component to realize the voice transmission and link management. The simulation and experiment show that the data processing core can offer sufficient processing capability and fixed processing delay. It has transparent transmission for Ethernet and data-voice co-transmission functions,good compatibility with the present tactical communication system.
