Abstract

The popular Ethernet protocol has gone through several generations, and each time the data rate   by a factor of 10. In this talk we look at the signal processing elements of the latest Ethernet design, the IEEE 802.3an standard for 10 Gbit/s over twisted-pair copper cables.

We will illustrate the challenges that the simple copper channel presents to high-speed data transmission, and discuss how these challenges were addressed in meeting the 802.3an standard speed and power requirements. In the course of this discussion we will see that with the advanced methods that are now part of modern transceiver designs the ultimate (Shannon) capacity of this channel has been practically reached. 

About the speaker

Christian Schlegel (Fellow, IEEE) held the iCORE Chair for Digital Communications at the University of Alberta, Edmonton, AB, Canada, from 2002 to 2012. Prior to that, he held academic appointments at the University of Hawaii at Manoa (visiting), Honolulu, HI, USA, at the University of South Australia, Adelaide, SA, Australia, at the University of Texas at San Antonio, San Antonio, TX, USA, and from 1996 to 2002 at the University of Utah, Salt Lake City, UT, USA. From 2004 to 2008, he also served as a Chief Technology Officer (part-time) of Aquantia Corporation, Milpitas, CA, USA, a start-up company building 10 Gbit/s Ethernet transceivers. He is the author of Trellis Coding (IEEE Press, 1997), Trellis and Turbo Coding (Wiley, 2004, 2015), as well as Coordinated Multiple User Communications (Springer, 2006). He is currently an NSERC Industrial Research Chair at Dalhousie University, Halifax, NS, Canada. His research interests include reliable digital communications for complex transmission environments. He was an Associate Editor for coding theory and techniques of the IEEE TRANSACTIONS ON COMMUNICATIONS from 1999 to 2007, a Guest Editor for the PROCEEDINGS OF THE IEEE, and currently serves on the Editorial Board of Hindawi Publishing. He received a U.S. National Science Foundation Career Award in 1997 and a Canada Research Chair in 2001. He served as a Technical Program Chair of the IEEE Information Theory Workshop 2001, the IEEE International Symposium on Information Theory 2005, the Symposium on Information Theory and its Applications 2016, and as the General Chair of the 2005 IEEE Communication Theory Workshop and the 2013 IEEE Conference on Wireless On-Demand Network Systems and Services. He was named the IEEE Distinguished Lecturer in 2007 and 2011.
