Abstract
Una unidad de abonado de radio (102) comprende un controlador (108) y un aparato receptor en diversidad de antena conmutada (106) que incluye unaprimera antena (114) y una segunda antena (116). La primera antena (114) está adaptada para recibiruna primera representación (158) de una senal deradiofrecuencia (156). La segunda antena (116) está adaaptada para recibir una segunda representación (160) de una senal de radiofrecuencia compuesta (156).El receptor (126), selectivamente acoplado ala primera antena (114) y la segunda antena (116), genera una sena recibida (153)en respuesta a la recepciónde por lo menos una de la primera representación (158) de la senal de radio frecuencia compuesta (156) desde la primeraantena (114) y la segundarepresentación (160) de la senal de radiofrecuencia (156) desde la segunda antena (116). El controlador (108), acoplada al receptor (126), acoplaselectivamente al receptor (126), en respuesta a la senal recibida (153),una d e: sólo la primera antena (114), sóla la seguanda antena (116) y tanto laprimera antena (114) como la segunda antena (116). La invención incluye un método para operar dicha unidad de abonado de radio (102).
