摘　　要：为便于学生从系统角度全面领悟和体会现代无线电设备工作原理,研制出基于软件无线电的通信系统实验平台。从硬件资源、片上系统、控制方法、射频电路、API接口、VITA-49协议等六方面,对实验平台设计思想和工作原理进行全面剖析。资源的开放化和软件化、结构的层次化和模块化、信号的高速化和宽带化、接口的分类化和层级化、操作的可控化和网络化等,是该实验平台的特点。该实验平台不仅易于开展分级实践教学,利于从不同起点和不同角度掌握现代无线电设备工作原理,而且能够发挥学生个性化创造性。本专题重点介绍实验平台主板上FPGA多重启动配置出片上系统的实现方法及片上系统基本工作原理。In order for students to fully understand the operating principles of modern radio equipment from system,a communication system experimental platform based on software radio is developed. The system-design thoughts and operating principles of the experimental platform are comprehensively explained in six aspects： hardware resources,system on programmable chip,control method,radio frequency circuit,application programming interface（ API） and VITA-49 protocol. Five characteristics of the experimental platform are concluded,those are the open and softwareoriented resources,the hierarchical and modularized structure,the high-speed and wide-band adaptive signal,the categorized and hierarchical interface,and the controllable and networked operation. After the experimental platform was adopted in teaching,we found that this experimental platform not only is good for developing hierarchic experimental teaching and is able to better develop students’ personalized creativity,but also makes easy for students to master the operating principles of modern radio equipment from different starting points and different perspectives. This topic focuses on the methods of configuring system on chip by FPGA multi boot and the basic operating principles of the system on chip in this experimental platform.
