At least one example embodiment discloses a method of determining crosstalk for at least one first line in a communication system having a plurality of second lines. The method includes obtaining at least one pilot matrix representing a sequence of pilot signals and transmitting pilot signals across the plurality of second lines in accordance with the at least one pilot matrix. The method further includes obtaining measurement vectors for the at least one first line on a plurality of subcarriers, in response to the transmitted pilot signals, determining a weighted vector, the weighted vector being a weighted combination of the measurement vectors and determining a crosstalk coupling vector based on the determined weighted vector.
