Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE CONSERVACION DE LA SINCRONIZACION TEMPORAL DE UNA ESTACION MOVIL RESPECTO A UNA ESTACION DE BASE, EN UN SISTEMA DE RADIOCOMUNICACION DIGITAL CELULAR QUE LLEVA DATOS EN FORMA DE TRAMAS Y ACCESO MULTIPLE POR REPARTICION EN EL TIEMPO. SEGUN LA INVENCION, ESTE PROCEDIMIENTO COMPRENDE LAS SIGUIENTES ETAPAS ITERATIVAS: MEDICIONES (1) DE UN DECALAJE FRECUENCIAL ENTRE LA FRECUENCIA PORTADORA DE EMISION DE LA ESTACION DE BASE Y LA FRECUENCIA DE LA PORTADORA DE EMISION DE LA ESTACION MOVIL; TRANSFORMACION (2) DE DICHO DECALAJE FRECUENCIAL EN UNA PRIMERA DERIVA TEMPORAL; CORRECCION (3) DE DICHA PRIMERA DERIVA TEMPORAL POR MODIFICACION DE LA LONGITUD DE AL MENOS UNA DE DICHAS TRAMAS; MEDICION (4) DE UNA SEGUNDA DERIVA TEMPORAL DEBIDO AL ALEJAMIENTO GEOGRAFICA ENTRE LA ESTACION DE BASE Y LA ESTACION MOVIL; CORRECCION (5) DE DICHA SEGUNDA DERIVA TEMPORAL POR MODIFICACION DE LA LONGITUD DE AL MENOS UNA DE DICHAS TRAMAS.
