The Application of New Far-end Crosstalk Cancellation in 10gbase-t*
نویسندگان
چکیده
In 10GBASE-T system, far-end crosstalk (FEXT) interference results in a considerable loss in decision point signal-to-noise ratio (DP-SNR). Thus IEEE 802.3an work group suggests that FEXT interference must be suppressed by at least 20 dB to achieve the DP-SNR requirement. This paper proposes a novel transmitter-side-based multiple-input-single-output (MISO) FEXT cancellation architecture. The coefficients of the MISO FEXT canceller and equalizer are obtained by using the least-mean-square adaptive method jointly. Simulation results show that the proposed method is able to suppress the FEXT interferences by 20.99 dB and the resulting DP-SNR is 7.36 dB higher than that of the traditional equalization method.

Adaptive Channel-shortened Interpolated Echo and next Canceller Designs Applied to 10gbase-t Ethernet System*
In this paper, new echo and NEXT cancellers are proposed for echo and NEXT cancellation in full-duplex digital transmission over 10GBASE-T system. The proposed cancellation schemes inherit the concept of the adaptive interpolated FIR (AIFIR)-based crosstalk canceller, where the long portion is modeled by an adaptive sparse FIR filter. Furthermore, we also employ the channel shortening technique...

Echo canceller plays an important role in the full-duplex communication system. Conventional implementations of echo cancellers are often the adaptive transversal filter architectures due to the simplicity and robustness of stability and convergence. However, the conventional echo cancellers suffer from high cost problem especially when the response time of the echo is long. In this paper, a ne...
متن کاملAnalysis of Simulation Methods for Far-end Crosstalk Cancellation
The information capacity of current digital subscriber lines is limited mainly by a crosstalk in metallic cables. The influence of near-end crosstalk (NEXT) can be well cancelled by frequency duplex method, but the elimination of far-end crosstalk (FEXT) is not so easy. Therefore FEXT is the dominant source of disturbance in current digital subscriber lines (xDSL). One of the most promising sol...

We study the application of multiuser MIMO precoding for the cancellation of far-end crosstalk (FEXT) in DSL systems. We present a novel approach where the FEXT is canceled in the time-domain which offers some significant advantages over the common frequency-domain cancellation techniques. The time-domain adaptive filters used to compensate for the FEXT on the the time-domain transmit signal ar...
