Abstract
Disclosed is a technique for estimating crosstalk between a first and second electrical transmission lines. The method comprises obtaining measurements of a received near end crosstalk, NEXT, signal, the NEXT signal being received at a first end of the second transmission line over a time period as a result of an electrical signal sent onto the first transmission line from its first end, the obtained measurements being in the time domain. Subsequently, a crosstalk coupling estimate is obtained per transmission line sub-interval by compensating the obtained measurements in the time domain of the received NEXT signal for round-trip attenuation of the sent signal from the first end of the first line to the sub-interval and back to the first end of the second line, and an estimate of a total crosstalk coupling is obtained by adding together at least some of the obtained crosstalk coupling estimates per transmission line sub-interval.
