Abstract

La presente invención se refiere a un método (30) para estimar las bies de frecuencia que afectan negativamente una señal digital representativa de un marco de símbolo, en donde dicho método (30) comprende las etapas de: (300) generar la señal digital en un periodo de muestreo Te que es más corto que un período predefinido de cada uno de los símbolos del marco; (302) calcular los valores de una pluralidad de pares de muestras de la señal digital, siendo cada valor representativo de una diferencia de fase entre las muestras de un par; (304) estimar las bies de frecuencia que afectan negativamente la señal digital en la base de los valores calculados para Np pares de muestras seleccionadas, de tal manera que una pluralidad de dichos Np pares pertenecen estrictamente a un solo símbolo en el marco. La presente invención se refiere además a un módulo (217) para implementar el método de estimación (30), así como a un método (40) y un sistema (1) de telecomunicación.
