Diseño, pruebas y evaluación de simulaciones de modulaciones digitales como enfoque práctico para la materia de comunicaciones inalámbricas de banda ancha.

Abstract

This curricular integration work aims to carry out the creation of a design in order to visualize, understand and evaluate digital modulations such as QAM, BPSK, QPSK and CDMA. The focus of this work is on academically strengthening students' knowledge in the subject of broadband wireless communications, through design, testing and evaluation of digital modulation simulations. The importance of simulation in the understanding and improvement of wireless technologies is highlighted, contextualizing its relevance in today's society. The need to close the gap between theory and practice in academic training is justified, establishing specific objectives that range from the design of simulations to the evaluation of speed and spectral efficiency. The focus is on the theoretical foundations of modulation, with special attention to QAM, BPSK, QPSK and CDMA, evaluating their spectral efficiency and transmission speed. The methodology used in this curricular integration work is based on MATLAB and combines analytical and empirical approaches. The MATLAB design of simulations for these modulations is detailed, including an interactive menu and extensive testing, providing valuable insights for each type of modulation. The importance of considering the relationship between modulation order, spectral efficiency and noise robustness is highlighted.
