Abstract

Las modalidades de la presente invención proponen un método y aparato de cuantificación vectorial de envolvente de frecuencia, en donde el método incluye: dividir N envolventes de frecuencia en una trama en N1 vectores, en donde cada vector en los N1 vectores incluye M envolventes de frecuencia; cuantificar un primer vector de en los N1 vectores utilizando un primer libro de códigos, para obtener una palabra de código correspondiente al primer vector cuantificado, en donde el primer de libro de código se divide en 2B1 porciones; determinar, de acuerdo con la palabra de código correspondiente al primer vector cuantificado, que el primer vector cuantificado está asociado con la i-ésima porción en las 2B1 porciones del primer libro de códigos; determinar un segundo libro de códigos de acuerdo con el libro de códigos de la i-ésima porción; y cuantificar un segundo vector en los N1 vectores con base en el segundo libro de códigos. En las modalidades de la presente invención, los envolventes de frecuencia se dividen en una pluralidad de vectores con menos dimensiones, de modo que la cuantificación vectorial se puede realizar en vectores de envolvente de frecuencia mediante el uso de un libro de códigos con una menor cantidad de bits. Por lo tanto, la complejidad de la cuantificación vectorial puede ser reducida, y también se puede garantizar un efecto de cuantificación vectorial.
