Abstract

EN UNA ESTACION BASE DE DIVERSIFICACION DE ANTENA DE UN TELEFONO SIN HILOS DECT SE DISPONE DE UN CAMBIO DE ANTENA, POR EJEMPLO BASADO EN CAMPOS DE MEDICION DE INTENSIDAD (FSM1, FSM2), EN DONDE SE DISPONE DE UNA DIVERSIFICACION DE ANTENAS PARA MEJORAR LA DIVERSIDAD DE ANTENA DURANTE LA RECEPCION DE INFORMACIONES DE RADIO DECT, POR EJEMPLO UNA PALABRA DE INTRODUCCION DE SINCRONIZACION (E-SEW) DE UN CAMPO (SYN) DE SINCRONIZACION DE APLICACION ESTANDAR DECT. DADO QUE EL CAMBIO DE ANTENA TIENE LUGAR DURANTE LA RECEPCION DE LA PALABRA (E-SEW) INTRODUCTORA DE SINCRONIZACION, TANTO LA DIVERSIDAD DE ANTENA OPTIMA Y LA TRANSMISION LIBRE DE INTERFERENCIAS DE LA INFORMACION UTILIZABLE EN EL MENSAJE DE RADIO SON POSIBLES EN TODAS LAS RANURAS DE TIEMPO DE TRANSMISION DE LA INFORMACION DE RADIO DECT.
