Abstract

EL DOMINIO DEL INVENTO ES EL DE LOS DISPOSITIVOS DE RECUPERACION DE FASE, DESTINADOS A EQUIPAR UN RECEPTOR, EN UN SISTEMA DE TRANSMISION NUMERICA, DEL TIPO CON ALTERNE, EN EL CUAL UN RECEPTOR NO RECIBE UNA TRAMA MAS QUE A INTERVALOS REGULARES. SEGUN EL INVENTO, EL DISPOSITIVO COMPRENDE UNOS PRIMEROS MEDIOS DE ENGANCHE DE FASE POR DETECCION DE ENERGIA (101) Y UNOS SEGUNDOS MEDIOS DE RECUPERACION DE FASE POR DETECCION (107) DE UN MOTIVO DE REFERENCIA, ASI COMO UNOS MEDIOS DE SELECCION DE UNA DE LAS INFORMACIONES DE DESFASAJE (113,118) LIBERADA POR LOS PRIMEROS MEDIOS DE ENGANCHE Y LOS SEGUNDOS MEDIOS DE RECUPERACION DE FASE , BAJO MANDO DE UNA INFORMACION BINARIA (121) DE PERDIDA O ADQUISICION DE ENCLAVAMIENTO DE SINCRONIZACION RESPECTIVAMENTE. APLICACION PREFERENCIAL A LA TRANSMISION CON ALTERNE BAJO CODIGO WAL2.
