Abstract

EN UN PROCEDIMIENTO PARA LA REDUCCION DE PERTURBACIONES DE UNA SEÑAL DE MENSAJE SE PROPONE UNA COMBINACION DE UNA COMPENSACION DE ECO DE ZONA DE FRECUENCIA CON UNA ELABORACION DE ZONA DE FRECUENCIA AMPLIA, CON PREFERENCIA UNA REDUCCION DE RUIDO Y/O UN RECONOCIMIENTO DE MENSAJE. EN LA ZONA DE FRECUENCIA SE REALIZA UNA ADAPTACION A LONGITUDES DE SEGMENTO DE SEÑAL DE TIEMPO EFECTIVAS DIFERENTES. ES ESPECIALMENTE VENTAJOSO LA RECONDUCCION DEL RESULTADO DE LA REDUCCION DE RUIDO PARA EL AJUSTE DEL FILTRO DE COMPENSACION DE ECO ADAPTIVO.
