A Novel Transmitter-Side-Based Far-End Crosstalk Cancellation For 10GBASE-T

In 100BASE-T system, far end crosstalk (FEXT) interference generates a considerable loss in decision point signal-to-noise ratio (DP-SNR). For this reason, FEXT interference must be suppressed by at least 20 dB to achieve the DP-SNR requirement of 23.4 dB. This paper proposes a novel transmitter-side-based multiple-input-single-output (MISO) FEXT canceller to cancel FEXT interference at the receiver side. The coefficients of MISO FEXT canceller and equalizer are obtained by using least-mean-square adaptive filter techniques in training mode. Our simulation results show that the proposed method is able to suppress the FEXT interferences by about 28 dB and outperforms the traditional FEXT cancellation method by about 7.67 dB.
