Abstract

Una unidad de abonado de radio (102) comprende un controlador (108) y un aparato en diversidad de antena conmutada (106) que incluye una primera antena (114) y una segunda antena (116). La primera antena (114) está adaptada para recibir una primera representacion (158) de una señal de radiofrecuencia (156). La segunda antena (116) está adaptada para recibir una segunda representacion (160) de una señal de radiofrecuencia compuesta (156). El receptor (126), selectivamente acoplado a la primera antena (114) y la segunda antena (116), genera una señal recibida (153) en respuesta a la recepcion de por lo menos una de la primera representacion (158) de la señal de radiofrecuencia compuesta (156) desde la primera antena (114) y la segunda representacion (160) de la señal de radiofrecuencia (156) desde la segunda antena (116). El controlador (108), acoplado al receptor (126), acopla selectivamente al receptor (126), en respuesta a la señal recibida (153) , una de: solo la primera antena (114), solo la segunda antena (116) y tanto la primera antena (114) como la segunda antena (116).
