Interference Cancellation (IFC) is a technique for reducing crosstalk
.The IFC technique is used
inDSL procedures to improve the interference voltage distance
and leads to an increase in thedata rate. In the IFC technique, the disturbed signal
ofa copper twisted pair
isanalyzed and the crosstalk is filtered out.
Compensation signals are calculated from the filtered signal using algorithms to compensate for the disturbed signal. The compensation signal is superimposed on the disturbed signal in real time. The real-time compensation method is also used in vectoring.
