System and Method for Time-Domain Equalization in Discrete Multi-tone Systems

摘要

A novel time-domain equalizer (TEQ) is provided for the receiver of a Discrete Multi-tone (DMT) system to shorten the length of the effective channel impulse response. The TEQ is based on a variant of the conventional decision-feedback equalizer (DFE) structure along with a training method for the TEQ settings. By using this DFE-based TEQ for DMT systems, the data symbols transmitted through the effective shortened channel would be more reliable.
