Abstract

La invención proporciona un sistema de comunicación (500), un sistema de iluminación, un método de transmisión de información y un producto de programa de computadora. El sistema de comunicación de acuerdo con la invención está configurado para transmitir datos mediante luz visible. El sistema de comunicación comprende un generador de señales (530) para generar una señal de impulsor de luz que es una señal modulada de desplazamiento de frecuencia que comprende una secuencia de partes de señal (215, 225), cada parte de señal es modulada en una primera o segunda frecuencia de acuerdo con los datos, las parte de señal son moduladas en la primera frecuencia que tiene primeros pulsos en primeros periodos y las partes de señal están moduladas en la segunda frecuencia que tiene segundos pulsos en segundos periodos. La energía de la luz visible correspondiente a un pulso en un periodo respectivo tiene el centro de gravedad en tiempo. Los pulsos de los periodos se colocan de manera que el centro de gravedad está en el centro del periodo para reducir los componentes de frecuencia perceptibles por el humano en la señal de impulsor de luz visible.
