Diseño e implementación de prácticas de laboratorio de telecomunicaciones aplicadas a la modulación y demodulación digital a través de la herramienta Matlab/Simulink.

Abstract

In the Telecommunications II area of the Electronic and Telecommunications career of the ESFOT, there aren’t laboratory practices and the lack of equipment to perform these practices doesn’t allow the student to have a wider knowledge combining theory with practice. In the ESFOT, the growth of students in the Electronics and Telecommunications career has been approximately 30% per annum "Source: Management Report March 2014". The implementation of laboratory practices will be elevating in the learning of modulation and digital demodulation. This project seeks to reinforce through practice the knowledge acquired through theory. Keeping the project as a learning tool will have a better understanding of the subject of Telecommunications II improving academic development. It is necessary to carry out laboratory practices to consolidate the theoretical knowledge acquired by analyzing the signals obtained in each of the modulation techniques studied. This tool is composed of a set of guides, 3 codes and 6 models with their respective interfaces, which will lead the student to a detailed investigation of the process, the interfaces have as function to assign the corresponding parameters in each of the blocks in a simple way. This work covers 3 types of ASK (Amplitude-Shift Keying), FSK (-Shift Keying) and PSK (Phase-Shift Keying). The implementation of this project allows observing the potential that Matlab / Simulink offer in the system modeling; in addition it compiles information about Matlab / Simulink which specifies the use of this tool in the communications area.
