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
