摘　　要：在高速数据传输系统中,基带数据经过编码、调制、上变频后生成射频信号,然后经过放大最后由天线发射出去。其中,数字接口模块是无线通信系统中的关键部分,直接影响了系统的性能。文章设计了一种无线通信系统数字接口模块,采用时分复用方式完成主站和从站之间高速数据传输,提出了基于FPGA实现数据传输协议,实现了UDP传输协议栈的数据包分层封装,针对不同的硬件平台以及不同的接口,设计了各个接口的驱动程序,为TDMA网络协议的正常运行、I/Q数据高速实时发送提供了基本保障。The baseband data in the high-speed data transmission system is encoded,modulated,and up-converted to generate a radio frequency signal,and the radio frequency signal is amplifi ed and fi nally transmitted through an antenna.Among them,the digital interface module is a key part of the wireless communication system,which directly affects the performance of the system.This paper designs a digital interface module for a wireless communication system that uses time-division multiplexing to complete high-speed data transmission between the master station and the slave station.It proposes a data transmission protocol based on FPGA and realizes the layered encapsulation of data packets of the UDP transmission protocol stack.For different hardware platforms and different interfaces,the drivers of each interface are designed to provide basic guarantee for the normal operation of the TDMA network protocol and the high-speed and real-time transmission of I/Q data.
