Abstract

Una unidad de abonado de radioteléfono celular de modalidad doble (802) caracterizada por un receptor en diversidad (812) y un controlador (814). Elreceptor de diversidad (812) recibe una primera senal de radiofrecuencia (808) modulada con un método de modulación digital (805) ó una segunda senal deradiofrecuencia modulada con un método de modulación analógico (807). En una realización, el controlador (814) controla el receptor en diversidad (812) enrespuesta a un primer algoritmo de diversidad(834) cuando el receptor en diversidad (812) recibela primera senal de radofrecuencia (808) modulada conel método de modulaciónn digital (805) y en respuesta a un segundo algoritmo de diversidad (837) cuando el receptor en diversidad (812) recibe la segundasenal de radiofrecuenica (810) modulada con el método de modulación analógico (807).En otra realización, el controlador (814) controla el receptor endiversidad (812) en respuesta a un primer conjunto de información recibida(835) cuando el receptor en diversidad (812) recibe la primera senal deradiofrecuencia (808) modulada con el método de modulación digital (805) y en respuesta a un segundo conjunto de información recibida cuando el receptor endiversidad (812) modulada con el método de modulación analógico (807).
