Simulation Based GNU Radio Tool for DSP Significant Learning.

This contribution presents an approach to strengthen the internalization of theoretical concepts related to digital signal processing - DSP and communications systems by means of active learning using the GNUradio framework, highlighting the experimental work in the strengthening of learning Results show that user implemented blocks have capabilities comparable to the ones included in GNU radio library and the student's requested feeling of"real life" deployments, with the advantage of being flexible, software dependent, multipurpose hardware, which can be used in the laboratory for teaching and further research. On the other hand, significantly learned materials can be retained for a relatively long period of time, months, even years
