Abstract
La invencion propone un sistema de transmision utilizando una subportadora de referencia para sincronizar un oscilador 104 local. La subportadora de referencia se puede colocar en diversas posiciones de la banda asignada a un operador. La unidad 1 externa del dispositivo de recepcion comprende un medio 107 de seleccion de pseudofrecuencia el cual posibilita seleccionar la subportadora de sincronizacion.
