Abstract

Un método para el procesamiento de una secuencia de valores suaves de acuerdo con un algoritmo de SISO (soft-input - soft-output, entradas-suaves - salidas-suaves) comprende llevar a cabo el procesamiento de ventanas deslizantes de la secuencia de valores suaves en una primera iteracion mediante la utilizacion de primeras colocaciones de ventanas y en una segunda iteracion mediante la utilizacion de segunda colocaciones de ventanas, y variándose las colocaciones de ventanas entre las iteraciones primera y segunda. En por lo menos una forma de realizacion, hay un circuito del receptor de comunicaciones configurado para llevar a cabo el procesamiento de SISO alternativo, en el que procesa una secuencia de valores suaves mediante el uso de ventanas deslizantes, y en el que varía las colocaciones de ventanas entre una o más iteraciones. El circuito receptor de comunicaciones comprende, por ejemplo, la totalidad o una parte de un circuito de turbo decodificacion o de otro tipo de circuito de decodificacion de bloques iterativos, un circuito de ecualizacion y decodificacion, un circuito de demodulacion y de decodificacion suaves, un circuito de deteccion y de decodificacion de multiples usuarios, o un circuito de deteccion y de decodificacion de multiples entradas-multiples salidas.
