The Reed-Solomon code and multidimensional TCM (MTCM) can be concatenated t
o improve the performance of discrete multitone (DMT) modulated digital sub
scriber line (DSL) systems. The criteria for designing an effective multidi
mensional TCM (MTCM) scheme with efficient interleaver are described The re
sults of simulations for evaluating the performance of the proposed coding
scheme are presented.
