ABSTRACT:
Fractional Spaced Equalizer FSEQ having adjustable coefficients ci for equalizing a reception signal of a transceiver. The transceiver comprises an echo compensator EC which generates an echo compensation signal for compensating an echo signal of the transceiver. The echo compensation signal is subtracted from the reception signal equalized by the fractional spaced equalizer FSEQ by means of a subtractor and the adjustable coefficients ci of the fractional spaced equalizer FSEQ are set after a half-duplex training phase of the transceiver during which the echo compensator EC is deactivated.
