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).Procedure for decoding a digitally transmitted broadcast signal containing data packets, in which the data packets are symbols and have a symbol duration (TS) in each case, the symbol duration (TS) being divided into a guard interval (TG) and an area of useful data (TU) and obtaining decoded data by decoding data transferred in the symbol duration (TS) within an evaluation window (2), detecting the start of each symbol e decoding being initiated after detection thereof so that the evaluation window (2) extends in the guard interval (TG) of the symbol duration (TS) of the symbol, in which the decoding is repeated several times by moving the titration window (2) for the entire symbol duration (TS), characterized in that the data obtained in repeated decoding are stored multiple times, are compared between yes and, by means of a valuation algorithm, an optimal position of the valuation window (2) is determined within the symbol duration (TS), not being present, in the optimal position of the valuation window (2), perturbations in the tool data area (TU) in the valuation window (2).
