Description

Discrete Multi Tone (DMT) is the modulation scheme used for Asymmetric Digital Subscriber Line (ADSL) systems and one of the modulation schemes used for Very high-speed Digital Subscriber Line (VDSL) systems.
Goal of the project is to implement the individual building blocks of a DMT transceiver, following ITU-T recommendation G.992.1 for ADSL systems.
