Abstract

A device for reducing mutual crosstalk of a signal routed across a first line and a second signal routed across a second line, wherein by the mutual crosstalk at an output of the first line a first interfered signal may be obtained and at an output of the second line a second interfered signal may be obtained, comprising a modifier for modifying the first interfered signal that is interfered by crosstalk due to the second signal, and for modifying the second interfered signal that is interfered by crosstalk due to the first signal, wherein the modifier is adapted to model an interference due to the mutual crosstalk, and a combiner for combining the first interfered signal with the modified second interfered signal to obtain a first corrected signal and for combining the second interfered signal with the modified first interfered signal to obtain a second corrected signal.
