Elaboración de objetivos de aprendizaje mediante el uso de los equipos USRP para la asignatura de Comunicaciones Inalámbricas

Abstract

The constant evolution of wireless communication technologies requires not only the acquisition of theoretical knowledge in students, but also the development of practical skills that contribute significantly to their professional training. The main objective of this research is to create and develop specific learning guides with a focus on competencies, for the Wireless Communications course, incorporating the Universal Software Radio Peripheral (USRP) devices that make it possible to carry out experimental practices focused on topics such as analogic modulation FM, frequency spectrum, signal propagation WAV, bandwidth, access protocols LabVIEW and transmission an d reception techniques, allowing students to interact directly with SDR systems, improving their skills in system design, analysis, simulation and validation of wireless systems. This thesis was developed as an FM audio signal transmission system using the National Instruments USRP-2920 transceiver. LabVIEW 2025 Q1 is used to program the signal flow, integrating blocks such as "Write TX," "Resample Waveforms," and "Sound File Read." The .WAV audio file is frequency modulated (FM). The FM signal was successfully sent and received, and with these results, three practical exercises were carried out at the telecommunications laboratory of the Salesian Polytechnic University on the Centenarian campus.
