Turbo-per-Tone Equalization for ADSL Systems

EURASIP Journal on Advances in Signal Processing, 2005
We study the equalization procedure in discrete multitone (DMT)-based systems, in particular, in DMT-based ADSL systems. Traditionally, equalization is performed in the time domain by means of a channel shortening filter.
