In this talk we will examine various digital communication blocks used in
broadband applications.
The focus of the talk will be on the Digital Subscriber Lines (xDSL) for
high-speed connections over the existing twisted pair copper lines.
These new technologies allow very high-speed data transfer ranging from
several KHz for HDSL to 10 MHz for ADSL and over 50 MHz for VDSL systems.
The talk will cover various modulation, line-coding, equalization, and
echo cancelation methods used for xDSL.

Center at Renton, WA, from 1985-86 and with Motorola Inc. Wireless
Technology Center from 1993-1995 (while on Sabbatical leave from OSU).
His current research activities includes design of high performance DSP
systems for communication applications, broadband communication systems,
VLSI system design for digital signal processing, and design of ASICs.
He has authored several book chapters and over 30 papers in communications,
signal processing, and mixed-signal CMOS ICs. Dr. Kiaei is a Senior Member
of the IEEE, and was a Member of the editorial board of IEEE Transactions
on Circuits and Systems-II. He is the General Chair of the International
Symposium on Low-Power Electronics and the Member of the technical program
committee of a number of several conferences (RFIC, VTC, VLSI/Signal
Processing, ISCAS, etc.). Dr. Kiaei is the recipient of the IEEE circuits
and Systems Society Darlington Best Paper Award in 1994, and was the recipient
of the Loyd-Carter Award for the the best teacher in the College of
Engineering at Oregon State University.
