An open communication teaching experiment system was proposed to solve experimental teaching hardware problems of embedded courses of communication engineering in colleges and universities. The system, based on software radio hardware architecture, was mainly composed of the base-band module and IF module. The base-band module using DSP + FPGA hardware solutions made full use of the advantages of the two processors and implemented flexibly communication digital algorithms, while the IF module, based on digital processing, could effectively change the baseband signal to IF analog signal. The graphical programming tools of MATLAB software was used in the display terminal to write applications. By operating the display and control terminal, users can configure according to projects of preinstalled experiment and realize the appropriate wireless communication system. The entire experimental system is universal, open, and hierarchical, so it can meet the requirements of experimental teaching with the embedded technology in communication.
