Abstract

Procedimiento para la descodificación de una señal de radiodifusión transmitida digitalmente que contiene paquetes de datos, en la que los paquetes de datos son símbolos y presentan una duración de símbolo (TS) en cada caso, estando dividida la duración de símbolo (TS) en un intervalo de guarda (TG) y un área de datos útiles (TU) y obteniéndose datos descodificados mediante una descodificación de datos transferidos en la duración de símbolo (TS) dentro de una ventana de valoración (2), detectándose el inicio de cada símbolo e iniciándose la descodificación tras la detección del mismo de modo que la ventana de valoración (2) se extiende en el intervalo de guarda (TG) de la duración de símbolo (TS) del símbolo, en el que la descodificación se repite varias veces desplazando la ventana de valoración (2) por toda la duración de símbolo (TS), caracterizado porque los datos obtenidos en la descodificación repetida múltiples veces se almacenan, se comparan entre sí y, por medio de un algoritmo de valoración, se determina una posición óptima de la ventana de valoración (2) dentro de la duración de símbolo (TS), no presentándose, en la posición óptima de la ventana de valoración (2), perturbaciones en el área de datos de útiles (TU) en la ventana de valoración (2).
