Abstract

Procedimiento para el procesamiento de datos recibidos con un receptor (16), en el que se reciben datos transmitidos en cuadros (k) consecutivos a través de un trayecto de transmisión (14), donde un cuadro (k) contiene un número predeterminado de posiciones binarias (I) en el que los datos recibidos son procesados con la ayuda de un algoritmo de probabilidad máxima a posteriori que utiliza incrementos métricos o del algoritmo de probabilidad máxima, donde los incrementos métricos para al menos una posición binaria (1), cuyo valor y/o su valor de fiabilidad (L(uk;I)) se correlaciona de un cuadro (k) a otro cuadro (k-1), son calculados en función de un valor de fiabilidad actual (L(uk;I )) determinado para el cuadro (k) procesado actualmente, que es una medida para la probabilidad de que el valor de la posición binaria (I) tenga un valor predeterminado, y en el que para el cálculo del valor de fiabilidad actual (L(uk;I )) se utiliza al menos un valor de fiabilidad observado (L ( b uk-1;I), (L( b uk;I)), que se determina a partir de un cuadro (k-1) ya procesado o a partir del cuadro (k) procesado actualmente para la posición binaria (I). caracterizado porque el valor de fiabilidad actual (L(uk;I)) se determina de tal manera que la suma, formada para varios cuadros (k), de las desviaciones de un valor de fiabilidad libre de error para el cuadro (k) respectivo y del valor de fiabilidad (L(uk;I)) calculado para el mismo cuadro (k) es mínimo.
