Diseño de un sistema múltiples entradas múltiples salidas para comunicaciones ópticas en espacio libre (FSO) como alternativa en los enlaces inalámbricos de última milla.

Abstract

The growing demand in the use of the Internet, the need to access a good quality service in places where access is often limited, makes Optical Communications in free space look like an alternative, based on this, the work analyzes the theoretical foundations of these systems and elaborate a design, the same one that consists of two models, the first one is based on internal optical modulation and the other works with external optical modulation. To execute the design and evaluate the performance, Matlab is used, thus carrying out tests with different signals and in different scenarios, Optisystem 16 allows simulating an FSO channel, where it is possible to vary: distance, attenuation, losses and others, analyzing these disturbances to determine the efficiency of these systems or indicate the parameters to change and improve it. For this research, the methods of analysis, synthesis and modeling will be worked on, in order to determine the efficiency of the system.
