Abstract

Método para codificar una señal de voz cuya señal comprende una secuencia de subtramas que contienen muestras de voz digitalizadas, comprendiendo dicho método, para cada sub-trama: (a) seleccionar un vector cuantificado d(i) que comprende al menos un impulso, donde el número m y la posición de impulsos del vector d(i) puede variar entre sub-tramas; (b) determinar un valor de ganancia gc para ponderar la amplitud del vector cuantificado d(i) o de un vector adicional c(i) derivado del vector cuantificado d(i), donde el vector ponderado sintetiza una señal residual ponderada e s; (c) determinar un factor de ponderación k que es función de la relación de un nivel de energía predeterminado respecto a la energía del vector cuantificado d(i); (d) determinar un valor de ganancia pronosticado gc apartir de una o más sub-tramas previamente procesadas, y como función de la energía Ec del vector cuantificado d(i) o de dicho vector adicional c(i) cuando la amplitud del vector es ponderada por dicho factor de ponderación k; y (e) determinar un factor de corrección de ganancia cuantificado gc utilizando dicho valor de ganancia gc y dicho valor de ganancia pronosticado.
