Construction and Teaching Practice of General Radio Experiment Platform Based on USRP

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.
