DMT Transceiver

## 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.  
  

## Features

\- Following ITU-T recommendation G.992.1 ADSL  
\- No trellis support  
\- No echo cancellation  
  
  
Phase 1, DMT Modem:  
  
\- Constellation encoder  
\- Gain  
\- IDFT  
\- Cyclic prefix  
  
\- TDQ  
\- Cyclic prefix  
\- DFT  
\- Constellation decoder

## Status

\- No active development
