Abstract

Las modalidades ejemplares describen un esquema de transmisión para usarse en un sistema de comunicación óptica por espacio libre (FSO) bidireccional. Cada nodo almacena localmente un bloque de datos transmitidos hasta que es recibido el reconocimiento de que fue descodificado apropiadamente. En el caso de que una descodificación no fuese exitosa, los datos son retransmitidos. El nodo receptor puede entonces agregar las señales recibidas para entonces intentar una descodificación sobre una señal combinada. El sistema también puede incluir controles dinámicos de modo que la señal retransmitida pueda ser optimizada para mejorar la probabilidad de una descodificación exitosa.
