Abstract

Un método de encubrimiento de error de trama basado en tramas que incluyen vectores de coeficiente de transformada incluyen las siguientes etapas: Rastrear (S11) los cambios de signo entre los coeficientes de transformada correspondientes de sub-vectores predeterminados de tramas estacionarias válidas consecutivas. Acumula (S12) el número de cambios de signo en sub-vectores correspondientes de un número predeterminado de tramas estacionarias válidas consecutivas. Reconstruye (S13) una trama errónea con la última trama estacionaria válida, pero con signos invertidos de coeficientes de transformada en sub-vectores que tienen un número acumulado de cambios de signo que excede un umbral predeterminado.
