Abstract

Se describe el procesamiento de la señal con base en el concepto de utilizar una trama interferida de dominio temporal (12, TDA) como una base para la segmentación temporal (14) y análisis espectral (16), realizando la segmentación temporal con base en la trama interferida de dominio temporal y realizando el análisis espectral con base en los segmentos de tiempo resultantes. La resolución temporal de la transformada de tiempo a frecuencia segmentada, total, puede de esta manera cambiarse adaptando simplemente la segmentación del tiempo para obtener un número adecuado de segmentos de tiempo con base en los cuales se aplica el análisis espectral. La serie completa de los coeficientes espectrales, obtenidos para todos los segmentos, proporciona una disposición en modo mosaico de frecuencia temporal seleccionable de la trama de señal original.
