HackRF + GNU Radio: A software-defined radio to teach communication theory [PDF]
International Journal of Electrical Engineering & Education, 2019 In this paper, an alternative to the traditional methodology related to signal processing-like subjects is proposed. These are subjects that require a deep mathematical and theoretical basis, but the practical goal is not often emphasized, which drives students to lose interest in the subject.
