Abstract
Se realiza un receptor mejorado de OFDM empleando una funcion de retardo simplificada para el canal de transmisiones. La funcion de retardo simplificada brinda una correlacion simplificada en el dominio de la frecuencia, que es aplicada para desarrollar la Matriz propia U, la cual es usada para desarrollar estimaciones de los canales. Esas estimaciones de canales son usadas en el receptor para desarrollar las senales de salida.
