Abstract

SE PRESENTA UN METODO Y UN APARATO PARA REDUCIR EL RUIDO EN UNA SEÑAL DE VOZ CAPAZ DE SUPRIMIR EL RUIDO EN LA SEÑAL DE ENTRADA Y SIMPLIFICAR EL PROCESAMIENTO. EL APARATO INCLUYE UNA UNIDAD DE TRANSFORMACION DE FOURIER, RAPIDA (3) PARA TRANSFORMAR LA SEÑAL DE VOZ DE ENTRADA EN UNA SEÑAL DE DOMINANTE DE FRECUENCIA, Y UNA UNIDAD DE CALCULO DEL VALOR HN (7) PARA CONTROLAR LAS CARACTERISTICAS DE FILTRO PARA EL FILTRADO EMPLEADO PARA ELIMINAR EL RUIDO DE LA SEÑAL DE VOZ DE ENTRADA. EL APARATO TAMBIEN INCLUYE UNA UNIDAD DE CORRECCION DE ESPECTRO (10) PARA REDUCIR LA SEÑAL DE VOZ DE ENTRADA MEDIANTE LA CONFORMACION DE FILTRADO CON RESPECTO A LAS CARACTERISTICAS DEL FILTRO PRODUCIDAS POR LA UNIDAD DE CALCULO DE VALOR HN (7). LA UNIDAD DE CALCULO DE VALOR HN (7) CALCULA EL VALOR HN SENSIBLE A UN VALOR DERIVADO DE LA RELACION SN MAXIMA BASADA EN EL MARCO DEL ESPECTRO DE LA SEÑAL DE ENTRADA OBTENIDA MEDIANTE LA UNIDAD RAPIDA DE TRANSFORMACION DE FOURIER (3) Y UN NIVEL DE RUIDO ESTIMADO Y CONTROLA EL PROCESAMIENTO PARA ELIMINAR EL RUIDO EN LA UNIDAD DE CORRECCION DE ESPECTRO (10) DEPENDIENTE DEL VALOR HN.
