Abstract

EL INVENTO SE REFIERE A UN PROCEDIMIENTO QUE SE UTILIZA PARA TRANSMITIR UNAS SEÑALES DISTRIBUIDAS EN UNA SUCESION DE BLOQUES SOLAPADOS A TRAVES DE VENTANA; CONSISTE EN: CONVERTIR LAS SEÑALES CONTENIDAS EN LOS BLOQUES EN UN ESPECTRO POR MEDIO DE UNA TRANSFORMACION; CODIFICAR EL ESPECTRO; TRANSMITIR EL ESPECTRO; DESCODIFICAR LA TRANSMISION; TRANSFORMAR LAS SEÑALES EN SEÑALES PARCIALES; JUNTAR LAS SEÑALES EN BLOQUES Y SOLAPAR LOS BLOQUES CONTENIENDO SEÑALES PARCIALES. SE CARACTERIZA PORQUE: LA ZONA DE SOLAPAMIENTO SE CEDE AL BLOQUE PARA PRODUCIR UN RESULTADO FINAL DE LAS FUNCIONES DE VENTANA Y SE SELECCIONA LA LONGITUD DE LAS FUNCIONES VENTANE SEGUN LA MODIFICACION DE SEÑALES, PARA IMPEDIR LA PERTURBACION EN BLOQUES CERNANOS, LA MODIFICACION DE SEÑALES Y ES APROPIADO PARA EL TRATAMIENTO DE SEÑALES DE VIDEO Y DE AUDIO SOMETIDAS EN LA TRANSMISION A UNA REDUCCION DE DATOS.
