Test signal generator for the evaluation of detection algorithms of the number of sources.

Abstract

The aim of this work is to design and implement a computational tool that allows generating, visualizing and configuring test signals required for the evaluation and comparison of detection algorithms of the number of sources. The software designed was based on a source generation model whose components were grouped into two sets: one dedicated to the waveforms generation and another one dedicated to the propagation channel. The programming of these components was done in MATLAB language. The implemented tool has two configurable modes of operation: the first one generates the test signals as a MATLAB function and the second one allows the user to visualize how the waveform of a test signal is formed, through a graphical interface. The proposed software is easy to use since the user only needs basic knowledge of signals to configure it, in addition, it allows creating the same scenarios to test and compare other detection techniques. The tool obtained is a convenient way to obtain test signals when you do not have the adequate equipment to generate them. The graphic interface implemented can be used as a virtual signaling laboratory for engineering students, since it allows observing the waveform that is modified by the elements present in the generation model.
