Abstract
Un procedimiento para eliminar ruido de convolución de una señal, comprendiendo el procedimiento: a. Caracterizar la señal con respecto a una pluralidad de bandas de frecuencia, teniendo la señal una potencia en cada banda de frecuencia; b. Calcular un logaritmo de una cantidad que caracteriza la potencia de la señal en cada banda de frecuencia en un intervalo especificado de tiempo para derivar una transformada de la señal en el dominio del espectro logarítmico; c. Ajustar un espectro suavizado de la potencia logarítmica a la transformada de la señal en el dominio del espectro logarítmico para derivar un espectro ajustado de la potencia logarítmica que se corresponde con el efecto del ruido de convolución en el dominio espectral logarítmico; d. Eliminar una función del espectro ajustado de la potencia logarítmica de la transformada de la señal en el dominio del espectro logarítmico.
