Design and implementation of a computationally efficient TEQ for DMT-based xDSL modem

This paper is concerned with a new algorithm which can be used to design a time-domain equalizer (TEQ) for xDSL systems employing discrete multitone (DMT) modulation. The proposed algorithm, derived by neglecting the terms which do not affect the performance of a DMT system in ARMA modeling, is shown to have a good performance compared with the previous TEQ algorithms even with a significantly lower computational complexity.
