Abstract
UNA SEÑAL, EN PARTICULAR UNA SEÑAL DE AUDIO, SE DIVIDE POR MEDIO DE VENTANAS EN BLOQUES CONSECUTIVOS QUE SE SUPERPONEN AL MENOS EN EL 50% Y LAS SECCIONES DE SEÑAL CONTENIDAS EN LOS BLOQUES SE EVALUAN POR MEDIO DE VENTANAS DE ANALISIS. LAS SEÑALES PARCIALES CONTENIDAS EN LOS BLOQUES SE TRANSFORMAN MEDIANTE UN PROCESO DE TRANSFORMACION QUE PERMITE LA COMPENSACION DE LOS COMPONENTES ALIAS, POR EJ., EL PROCESO DE "TIME DOMAIN ALIASING CANCELLATION" (CANCELACION DEL ALIAS DE DOMINIO DE TIEMPO) , Y LOS ESPECTROS RESULTANTES DE LA TRANSFORMACION ENTONCES, SE CODIFICAN Y SE TRANSMITEN. DESPUES DE LA TRANSMISION, SE DECODIFICAN Y SE RECONVIERTEN EN SEÑALES PARCIALES MEDIANTE TRANSFORMACION POSTERIOR. LOS BLOQUES CONTENIENDO LAS SEÑALES PARCIALES SE EVALUAN ENTONCES POR MEDIO DE VENTANAS DE SINTESIS Y SE JUNTAN DE NUEVO EL UNO AL OTRO DE TAL MANERA QUE SE SOBREPONEN. LAS FUNCIONES DE VENTANA DE LAS VENTANAS DE SINTESIS SE PUEDEN DETERMINAR EN FUNCION DE LAS FUNCIONES DE VENTANA LIBREMENTE SELECCIONADAS DE LAS CORRESPONDIENTES VENTANAS DE ANALISIS EN LA ZONA DE SUPERPOSICION UTILIZANDO LAS ECUACIONES DADAS EN LA DESCRIPCION. EL PROCESO PERMITE UNA BUENA RESOLUCION DE FRECUENCIA, QUE ES UN REQUISITO PREVIO PARA LA REDUCCION DE DATOS EFICAZ.
