Abstract

VDSL(Very-high-rate Digital subscriber Line) have a severe FEXT(Far-End Crosstalk). This paper proposes FEXT cancelation scheme in VDSL system. The scheme is GDFE(Generalize Decision Feedback Equalizer) and Vectored-DMT (Discrete Multitone). Feedback part of GDFE decreases FEXT noise. Canceler and Precoder block a part of Vectored-DMT eliminate FEXT. After all, simulation result show improvement of transmit and receive speed.
