Abstract

La presente invencion enseña un método para la codificacion de datos de coeficiente predictivo lineal. La presente invencion transforma el dato de coeficiente predictivo lineal en un dato de coseno de espectro de línea (103). El dato de coseno de espectro de línea se utiliza para generar dos vectores definidos de manera recurrente (104). Los vectores definidos de manera recurrente se utilizan para calcular un conjunto de valores de autocorreccion de sensibilidad (106a-16N) y un conjunto de correlacion de cruce de sensibilidad (107a-107N). Los valores de coseno de espectro de línea se utilizan para calcular un conjunto de valores de raíz cuadrada de espectro de línea.
