ADSL per-tone/per-group optimal equalizer and windowing design

An overview of existing and new techniques to maximize the achievable bit rate of discrete multi tone (DMT) based modems is presented. The presented methods focused on equalization and/or mitigation of narrowband interference using receiver windowing. The algorithms can be used in a per group equalization and/or windowing scheme, which has intermediate performance between a single time domain equalizer (TEQ)/a single window and a per tone equalizer.
