GNU Radio and USRP for Problem-Based Learning in Communications: Case Studies in Cellular Phone Jamming and Modulation Classification

摘要

The GNU Radio and USRP are important tools that can be used by students to learn the theory of various areas, such as digital signal processing and telecommunications. This work presents how the GNU Radio and USRP has been used to transmit/receive signals in wired and wireless channels for a wide range of frequencies. Two case studies are discussed: cellular phone jamming and modulation classification. When dealing with these two (and other) topics, the students get involved with several important theoretical as well as practical issues. The work summarizes strategies to benefit from the combination of GNU Radio and USRP and increase their impact on engineering education.
