Resumen
La comunicación por luz visible es una tecnología de nuevo desarrollo que se ha planteado como
una alternativa a los actuales sistemas de comunicación basados en electromagnética. Los
estudios realizados recientemente llevaron al uso de la tecnología led para fines de iluminación y
para que esta tecnología tenga una ventaja sobre los dispositivos que consumen energía excesiva
como actualmente siendo utilizado por nosotros. Se están realizando estudios para utilizar leds de
manera efectiva como antena transmisora de transmisión óptica y aplicación de técnicas de
modulación utilizadas en sistemas electromagnéticos a la tecnología VLC con el fin de lograr
resistencia contra ruido blanco, reflejos, refracciones y ecos. En esta tesis, se utilizó una sala vacía
en forma de prisma rectangular de dimensiones predeterminadas con paneles de led, en número y
posición previamente determinados, que enviaban datos, por lo que, la respuesta al impulso
mostrada por el canal hasta los datos enviados que llegaban al fotodetector se analizaba según
diferentes ángulos de FOV en entorno informático y posteriormente, los datos se enviaban al
receptor a través de estos canales que tienen diferente respuesta al impulso en función de los
grados de FOV específicos. Los resultados de la simulación se han mostrado en gráficos de
cambio de tasa de error de bits basado en SNR, y se ha observado que el filtro adaptativo en el
que se utiliza el algoritmo RLS proporcionó mejores resultados que el filtro adaptativo en el que
se utilizó el algoritmo LMS.
Visible light communication is a newly developed technology that has been proposed as an alternative to current electromagnetic-based communication systems. Recent research has shown that LED technology is being used for lighting purposes and that this technology has advantages over the high power devices we currently use. Research is currently underway to efficiently use LEDs as transmitting antennas for light transmission, and to apply modulation techniques used in electromagnetic systems to VLC technology to achieve immunity to random noise, reflections, refractions, and echoes. In this work, a blank space was created in the form of a rectangular prism of a given size using predetermined numbers and positions of LED panels, and data was sent. Thus, the impulse response appears through the channel to the data sent.
