Capacidade de diversidade de sistemas SISO vs. MIMO: impacto no desempenho em cenários urbanos

Abstract

This undergraduate final project aimed to compare SISO and MIMO systems in terms of spatial diversity in urban environments. The study proved to be relevant to the existing wireless communications literature by providing a comparative analysis that can serve as a foundation for future research and innovations in the field. In SISO systems, spatial diversity is limited to a single transmit and receive antenna. In contrast, MIMO systems employ multiple antennas to exploit various propagation paths. To conduct this analysis, simulations were carried out to evaluate the performance of both systems using metrics such as BER and Eb/N0. Based on the results obtained, the superiority of the MIMO system in terms of efficiency and reliability was demonstrated, especially in environments with high levels of interference and multipath propagation. This analysis was crucial to addressing the growing demands of modern society, pointing to the development of faster and more robust wireless communication networks, which are essential for the implementation of emerging technologies such as 5G, smart cities and IoT.
