Abstract

Se efectuo una estimacion de datos basada en una ventana deslizable. Se introduce un error de estimacion de datos debido al modelo de comunicacion que modela la relacion entre las senales transmitidas y recibidas. Para compensar un error en los datos estimados, son usados los datos que fueron estimados en el paso de ventana deslizable anterior (58) o terminos que en otras circunstancias serian truncados como ruido. Esas tecnicas (50, 52, 54, 56, 58, 60, 62 y 64) permiten que los datos sean truncados antes de un procesamiento adicional reduciendo los datos de la ventana.
