Abstract
Se da a conocer un aparato para la codificación de una señal de voz mediante la determinación de un vector de libro de códigos de un algoritmo de codificación de voz. El aparato comprende un determinador de matrices (110) para determinar una matriz de autocorrelación R, y un determinador de vectores de libros de códigos (120) para determinar el vector de libro de códigos dependiendo de la matriz de autocorrelación R. El determinador de matrices (110) está configurado para determinar la matriz de autocorrelación R mediante la determinación de coeficientes de vector de un vector r, donde la matriz de autocorrelación R comprende una pluralidad de filas y una pluralidad de columnas, donde el vector r indica una de las columnas o una de las filas de la matriz de autocorrelación R, donde R(i, j) = r(|i - j|) donde R(i, j) indica los coeficientes de la matriz de autocorrelación R, donde i es un primer índice que indica una de una pluralidad de filas de la matriz de autocorrelación R, y donde j es un segundo índice que indica una de la pluralidad de columnas de la matriz de autocorrelación R.
