Abstract

Procedimiento de estimación de un desfasaje parásito durante la recepción de una señal multiportadora formada por una sucesión temporal de símbolos que modulan una pluralidad de frecuencias portadoras, llevando al menos, algunas frecuencias portadoras de, al menos, algunos de los citados símbolos, elementos de referencia cuyo valor en la emisión es conocido por el receptor que efectúa la citada recepción, procedimiento del tipo que comprende un paso (3) de estimación de la variación de fase deltan entre, al menos, dos símbolos que llevan elementos de referencia, por análisis de los citados elementos de referencia, caracterizado porque la contribución (Rn, k) de, al menos, algunos de los citados elementos 10 de referencia en la citada estimación (3) es ponderada por una información (a2k) representativa del ruido que afecta a la frecuencia portadora que lleva el citado elemento de referencia.
