中文摘要：
通信、雷达、广播、电视等无线电系统在电磁波信号的收发和处理上具有相似的特点。该文介绍了通用软件无线电外设平台（USRP）的由来与特点、系统架构、实验开发、课程应用和教学实践状况。同时,该文利用软件无线电技术建立了无线电系统的通用硬件平台,以软件方式实现功能的重构,使多门无线电类课程能够共享相同的实验平台。学生在该平台上可快速建立不同的无线收发系统,从系统的层面掌握无线电系统的设计,加深对理论的理解和感性认识。
英文摘要：
Communication,radar,broadcast,TV and other wireless systems are similar in transmitting,receiving and processing of electromagnetic signals. General hardware platform is constructed for these systems with software defined radio techniques. Functions are redefined by changing software. So it is possible to share same platform by many radio courses. Students can build their radio systems fast on the platform,learn to design radio system and understand corresponding knowledge by themselves. This paper introduces the origin,features,structures,experiments,and teaching situation based on USRP.
