Signal processor implementation of DMT based VDSL modems
A. Lakhzouri, Markku Renfors · 2002
The discrete multi-tone (DMT) modulation is considered a viable technique for high-speed digital transmission over a subscriber loop. It was selected as the standard for ADSL modems and it is also a strong candidate in the VDSL area. This paper investigates a programmable solution for DMT-based VDSL modems using the Texas Instruments' processor family TMS320C62xx. A structure for both transmitter and receiver sides is presented. Synchronization and equalization issues are also discussed.
