Abstract:
Systems and methods for reducing crosstalk are provided. In one implementation, a method is provided. The method includes applying a pilot signal to a disturber twisted pair and measuring near end crosstalk of a victim twisted pair. The coupling characteristics between the disturber and the victim twisted pair are determined. A far end crosstalk function is derived for estimating the far end crosstalk in the victim twisted pair using the determined coupling characteristics. A crosstalk reduction signal is determined using the estimated far end cross talk. The crosstalk reduction signal is injected into the victim twisted pair to reduce crosstalk in the victim twisted pair.
