ADSL Transceiver Design at UT Austin

This freely distributable toolkit provides a graphical user interface and functions in LabVIEW to simulate a discretized multicarrier wired communication system. The structure and default parameters of the transmitter, channel model, and receiver follow the ADSL2 ITU-T G.992.3 standard, which provides asymmetric two-way high-speed wired data communication. The downstream direction indicates the higher data rate direction, and the upstream indicates the lower data rate direction. The simulation is in National Instruments LabVIEW software. A standalone executable of the simulation that runs on a PC without needing a LabVIEW license is also available in the releases.

Slides describing the simulator entitled "Design and Simulation of ADSL2 Transceivers Using LabVIEW" (August 9, 2006) are available in PowerPoint format. Also, please see the following report "High-Speed Wireline Communication Systems" (May 31, 2005) that provides a brief overview of the ADSL2 and ADSL2+ standards.

Directions to Run the Simulator

Two options to run the simulator:

According to the G.992.3 standard's support for trellis coding, there must be even number of "one bit" subchannels and odd number of "zero bit" subchannels in the Bit Allocation Table.

To obtain help about any parameter setting (control) or display (indicator), move the mouse over its text/icon, and the help information should appear in the context help window. The context help window can be opened by hitting Ctrl-H.
