| Bibliography: | GNU radio; signal analysis and processing; exploratory experiments ZHANG Jianliang, QI Donglian, WU Yue, HAN Tao, YAO Wei （ College of Electrical Engineering, Zhejiang University, Hangzhou 310027, China） 31-1707/T According to characteristics of the experimental course teaching practice of signal analysis and processing,based on the open-source GNU Radio software architecture,an open,innovative exploratory experiment teaching platform is designed. By using the high efficiency C ＋ ＋ language to implement various signal processing module（ block）,the basic theory in the course,including filters,FFT transform,modulator/demodulator,channel codec module,can be easily implemented. By using the scripting language Python to construct flow graph,the signal processing blocks can be easily connected into a complete signal processing system; also,based on the practice of scientific research projects of teachers,a variety of application-oriented exploratory experiments can be carried out. By exploring the experiments in the f |
