Abstract
Un metodo de comunicacion inalambrica que explota el ambiente fisico de radio frecuencia (RF) para establecer un numero suficiente de vias multiples utilizables de propagacion de RF para facilitar las comunicaciones. El metodo se implementa en un sistema de comunicacion inalambrica que incluye al menos un transmisor y al menos un receptor. La antena del receptor se dirige hacia una de una pluralidad de vias de recepcion y recibe una corriente de datos del transmisor a traves de la via de recepcion hacia el cual se dirige la antena del receptor. El receptor decodifica la corriente de datos, reconstruye un patron de modulacion de la corriente de datos decodificada, y sustrae la corriente de datos reconstruida a partir de una suma de todas las senales recibidas por el receptor a traves de las vias de recepcion. El receptor proporciona al transmisor la informacion de la direccion de la senal recibida asociada con las vias de recepcion. El transmisor ajusta y/o elimina una o mas de las vias de recepcion que no son utilizables con base en la informacion de la direccion de la senal.
