Utilização de rádio definido por software para análise de sinais aplicados ao ensino em engenharia

Abstract

The Software Defined Radio is revolutionizing the concept of signal processing devices. The Software Defined Radio provides a radio architecture that allows flexible switching of the radio function, possibly in real time, with a process that ensures a desired quality of service. This flexible hardware architecture combined with flexibility in software architecture allows integration with networks and with totally different interfaces. From this concept, this work presents applications using the Universal Software Radio Peripheral and the GNU Radio software as a proposal to equip telecommunications, biomedical, electrical and electronic laboratories. Also, this work presents the creation of new processing blocks using the GNU Radio, with the goal of applying the Daubechies Wavelet Transform to analyze cardiac signals and also for voice signals processing in order to perform file compression.
