Abstract
Digital Subscriber Lines (DSL) technology
provides a transport of high-bit-rate digital information
over the public telephone lines. Recently, a new technique
has been proposed to increase the overall data rate by
coordinating all the wires in the same DSL cable. However,
this coordination method cannot be applied when the cable
lines are used for different types of xDSL services. This
paper proposes a multi-dimensionsal decision-feedback
equalizer (M-D DFE) and precoding method that can
simultaneously coordinate the lines in the time and user
domain. A modified decision-feedback substitution is
proposed by applying a generalized DFE (G-DFE) scheme
into the two dimensional domain to increase the cable
capacity. The performance of the proposed scheme is
verified by computer simulation.
