Abstract

EN UN ECUALIZADOR DEL TIPO DFE (DECISION FEEDBACK EQUALIZER) PARA REALIZAR LA ECUALIZACION EN UN RECEPTOR PARA SEÑALES ELECTROMAGNETICAS QUE HAYAN PASADO UN CANAL DE TRANSMISION, SE USA UNA PLURALIDAD DE FACTORES DE COMPENSACION O COEFICIENTES DE DERIVACION EN UNA PARTE DE LA CORRECCION ANTICIPANTE ASI COMO EN UNA PARTE DE LA REALIMENTACION. SE SELECCIONAN LOS VALORES BASADOS EN UNA ESTIMA DE LA RESPUESTA DE IMPULSO DEL CANAL COMO CONDICION DE COMIENZO DE ESTOS COEFICIENTES. LOS VALORES DE ESTIMACION SE USAN EN UN ESTADO COMPLEJO CONJUGADO EN LA PARTE DE LA CORRECCION DE ANTICIPACION, QUE SE CORRESPONDE CON UN FILTRO EQUILIBRADO, Y LA AUTOCORRELACCION DE LA ESTIMACION DE LA RESPUESTA DE IMPULSO DEL CANAL SE USA EN LA PARTE DE REALIMENTACION. LA DETECCION DE LOS BITS DE DATOS PUEDE COMENZAR EN UNA SECUENCIA TRASERA OPCIONAL Y PROCEDE DE ESTA. LA ESTIMACION DE LA RESPUESTA DE IMPULSO DEL CANAL PUEDE TAMBIEN USARSE PARA LA SINCRONIZACION, Y LAS SEÑALES RECIBIDAS PUEDEN SER AJUSTADAS EN FASE OFRECUENCIA ANTES DE LA DETECCION.
