Abstract

Un codificador (100) para codificar predictivamente una señal (105) que tiene una secuencia de valores de señal (s(n)) comprende un predictor (110) para realizar una predicción adaptativa dependiente de la señal (105) (s(n)), y dependiente de uno o más valores de ponderación (111) (wi), para obtener valores de señal previstos (115) (s’(n)), en donde el predictor (110) está configurado para reestablecer los valores de ponderación (111) en los tiempos que dependen de la señal (105), y en donde el predictor (110) está configurado para ajustar los valores de ponderación (111) a la señal (105) entre los reajustes posteriores.
