Abstract

Un controlador de vectorización (130) para estimar al menos un coeficiente de diafonía a una frecuencia de portadora dada (k) a partir de al menos una línea perturbadora respectiva (Lm) hacia una línea víctima (Ln) de un grupo de vectorización, y configurado para asignar al menos una secuencia de sondeo de diafonía (Smt (k)) de entre un conjunto de secuencias de sondeo de diafonía ortogonales (131) a la al menos una línea perturbadora respectiva para la modulación a la frecuencia de portadora dada de al menos una secuencia respectiva de símbolos de sondeo de diafonía, para recibir unas muestras de error (Ent (k)) según se miden de forma sucesiva por un receptor (210n) acoplado con la línea víctima a la frecuencia de portadora dada mientras que la al menos una secuencia de símbolos de sondeo de diafonía se están transmitiendo a lo largo de la al menos una línea perturbadora respectiva, caracterizado porque el controlador de vectorización está configurado adicionalmente para correlacionar las muestras de error recibidas con al menos una secuencia de sondeo de diafonía sin asignar (Tmt (k)) de entre el conjunto de secuencias de sondeo de diafonía ortogonales para la detección de un error de anulación de correspondencia en las muestras de error recibidas, la al menos una secuencia de sondeo de diafonía sin asignar no siendo usada activamente por línea alguna del grupo de vectorización durante la transmisión de la al menos una secuencia de símbolos de sondeo de diafonía a lo largo de la al menos una línea perturbadora respectiva.
