Abstract :
Crosstalk is the major limiting factor affecting the achieve rate of VDSL/VDSL2 system. Several crosstalk cancelers from frequency domain have been proposed. However, these kinds of processing suffer from high computational complexity. This paper considers the crosstalk cancellation from time domain, a two stage adaptive filter is designed to cancel the crosstalk. Computer simulation results based on measured data verify the efficiency of the proposed method.
