Abstract

En un sistema de comunicacion, se describe un metodo para calcular una senal transmitida. Se recibe una senal de comunicacion. Un analizador de potencia de retardo analiza la senal de comunicacion. Se calcula posteriormente el retardo en el despliegue de tiempos de propagacion a partir de la informacion obtenida del analizador de potencia de retardo. Se determina la nueva longitud del filtro del ecualizador en base al retardo en el despliegue de los tiempos de propagacion calculado. Se configura un ecualizador para utilizar la nueva longitud del filtro del ecualizador.
