摘　　要：根据正交频分复用(OFDM)接收机处理数据的高速传输需求,设计一种基于FPGA万兆以太网的高速传输系统。系统对子带、窄带和频谱子信道数据进行处理和储存,按照规定的自定义协议将数据组包,采用UDP/IP协议栈对数据包网络数据打包,通过万兆光口传输至服务器。测试结果表明,该方案能够通过指定的协议高速实时地将多种信道化数据传输至服务器,实时传输速率高达5.7千兆字节/秒。该系统稳定性高、数据实时性高、控制时序精确,适合作为OFDM接收机处理数据的传输系统。A high-speed transmission system based on FPGA 10 Gigabit Ethernet is designed based on the need for highspeed transmission of data processed by orthogonal frequency division multiplexing(OFDM)receivers.The system processes and stores subband,narrowband and spectral sub-channel data,groups the data into packets according to the specified customized protocols,packages the packet network data by the UDP/IP protocol stack,and transmits them to the server through the 10 Gigabit optical port.Test results show that the scheme can transmit multiple channelized data to the server in high speed and real time through the specified protocols,with a real-time transmission rate of 5.7 Gbyte/s.The system has high stability,real-time data,and precise control timing,making it suitable as a transmission system for processed data by OFDM receivers.
