Abstract

Se describen metodos y aparato para utilizar senales angostas de alta potencia, por ejemplo, tonos, para comunicar informacion del transmisor sin poner toda la potencia de transmisor a disposicion en el tono o tonos transmitidos; los datos de usuario son transmitidos en paralelo con la informacion del transmisor en muchas modalidades, en donde a los datos de usuario se les asigna mas del 20% de la potencia de salida maxima del transmisor en muchos casos; al utilizar una cantidad de potencia en los tonos empleados para comunicar informacion del transmisor al mismo tiempo que de manera simultanea se transmiten datos del usuario con mas del 20% de la potencia de transmision disponible, se logra la utilizacion eficiente del ancho de banda al mismo tiempo que se sigue garantizando una alta probabilidad de que las senales de informacion del transmisor seran recibidas y detectables utilizando tecnicas simples de deteccion de energia y sin la necesidad de que se logre sincronizacion de temporizacion con el transmisor para la interpretacion exitosa de la informacion del transmisor.
