Abstract

SE MAPEA UNA SECUENCIA DE DATOS DIGITALES DENTRO DE UNA SECUENCIA DE PUNTOS DE SEÑALES PARA TRANSMISION DE DATOS SOBRE UN CANAL, CARACTERIZADO POR UNA RESPUESTA NO IDEAL. LA SECUENCIA DE PUNTOS DE SEÑALES SE SELECCIONA DE UN SUBCONJUNTO DE TODAS LAS SECUENCIAS POSIBLES DE PUNTOS DE SEÑALES, BASANDOSE EN LA SECUENCIA DE DATOS DIGITALES Y AL OBTENER LA RESPUESTA. TODAS LAS SECUENCIAS POSIBLES DE PUNTOS DE SEÑALES EN EL SUBCONJUNTO SE APOYAN EN UNA REGION FUNDAMENTAL DE UN CODIGO DE ENREJADO FILTRADO. LA REGION FUNDAMENTAL ES DISTINTA DE UN PRODUCTO SIMPLE CARTESIANO DE REGIONES DIMENSIONALES LIMITADAS.
