Implementações práticas de DSP e RF com GNURadio e HackRF One

Abstract

This is an introductory and practical research work aimed at the areas of digital signal processing and the transmission and reception of radio frequency signals. The goal is that it becomes a starting point for students of electronic and telecommunications engineering to have a first practical contact with digital signal processing techniques applied from a software-defined radio system. The proposal for carrying out the experiments relies on the use of programming methods and techniques in C++/Python for the construction of modules and signal processing blocks together with the use of a hardware (SDR HackRF One) dedicated to the purpose of being the interface between a computer and the radio frequency frontend. During the work, details of implementation, communication between hardware and provisioning of the environment and the software tools necessary for its realization are demonstrated. All directed efforts resulted in the successful demonstration of the practical use of the GNURadio tool, as well as the possibility that the engineer also acts as a developer, which brings extremely beneficial gains to his learning and professional specialization, in addition to the possibility of applying of the theoretical concepts acquired about signals and systems, digital signal processing, programming of high criticality systems, communication systems, modulation and demodulation and etc . . .
