Abstract

The invention relates to an interference compensator device for compensating for interference signals on two-wire lines of communications systems, whereby a useful signal (S1) and the inverted useful signal (S2) are connected to a transmitter (UE) via a first line (L1) a second line (L2), respectively. The inventive interference compensator device comprises: a first differential signal generating device (D1), which is connected to the transmitter (UE) and which is provided for generating a first differential signal between the signals transmitted on the first and second line (L1, L2); a delay device (30) for delaying the differential signal; a first summation signal generating device (SU1) for generating a first summation signal of the signals transmitted on the first and second line (L1, L2); an interference estimating device (50) for estimating an interference signal, which is contained in the differential signal, based on the first summation signal, and; a second differential signal generating device (D2) for generating a second differential signal between the first differential signal and the estimated interference signal for compensating for the interference signal. The interference estimating device (50) has an adapted non-recursive digital filtering device.
