Method and system for estimating crosstalk between electrical transmission lines

A system configured for estimating crosstalk between a first electrical transmission line and a second electrical transmission line, the system comprising a processor and a memory, said memory containing instructions executable by said processor, whereby the system is operative for:

• 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 a time domain;
• obtaining a crosstalk coupling estimate 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
• obtaining an estimate of a total crosstalk coupling by adding together at least some of the obtained crosstalk coupling estimates per transmission line sub-interval.

A non-transitory computer readable storage medium storing one or more instructions to be run in a system, for estimating crosstalk between a first electrical transmission line and a second electrical transmission line, which the one or more instructions when run in the system causes the system to perform the following steps:

• 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 a time domain;
• obtaining a crosstalk coupling estimate 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
• obtaining an estimate of a total crosstalk coupling by adding together at least some of the obtained crosstalk coupling estimates per transmission line sub-interval.

A system configured for estimating crosstalk between a first electrical transmission line and a second electrical transmission line, the system comprising:

• a first obtaining module for 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 a time domain;
• a second obtaining module for obtaining a crosstalk coupling estimate 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
• a third obtaining module for obtaining an estimate of a total crosstalk coupling by adding together at least some of the obtained crosstalk coupling estimates per transmission line sub-interval.
