Abstract
In this second part we discuss the ``turbo equalizers'' that result from iterating soft information in an iterative receiver. These equalizers are a very powerful methodology for signaling in highly interference-limited environments. We will discuss the potential application of such systems and their performance. Finallly, we will briefly address the application of spatial coupling to turbo equalizers, and show that, under certain assumptions they can achieve the Shannon capacities of the respective communications channels with a complexity that scales only linearly in the size of the system. Mathematical details of spatial coupling as well as potential implementation avenues for highly efficient modern iterative communications systems are also discussed if time permits.
About the Speaker
Christian Schlegel received the Dipl. El. Ing. ETH degree from the Federal Institute of Technology, Zürich, and the M.S. and Ph.D. degrees in electrical engineering from the University of Notre Dame, Notre Dame, IN. He currently holds an NSERC Industrial Research Chair at Dalhousie University. From 2002-2012, Dr. Schlegel was iCORE Chair for Digital Communications at the University of Alberta, Edmonton, Canada. Prior to that, he held academic appointments at the University of Hawaii at Manoa (visiting), the University of South Australia in Adelaide, Australia, the University of Texas at San Antonio, and from 1996-2002 at the University of Utah, Salt Lake City. From 2004-2008 he was CTO of Aquantia Corporation, Milpitas, CA, a start-up company building 10Gbit/s Ethernet transceivers. Professor Schlegel is the author of "Trellis Coding'' (1997, IEEE Press), "Trellis and Turbo Coding,'' (2004 Wiley/IEEE), and "Coordinated Multiple User Communications,'' (2006 Springer). Dr. Schlegel received a US National Science Foundation Career Award in 1997, a Canada Research Chair in 2001, and a Province of Alberta iCORE Chair in 2001 and 2006. He was named IEEE Distinguished Lecturer in 2007 and 2011, and is an IEEE Fellow.
Dr. Schlegel was associate editor for coding theory and techniques for the IEEE Transactions on Communications from 1999-2007, guest editor for the Proceedings of the IEEE, and currently serves on the editorial board of Editorial Board of the Journal of Electrical and Computer Engineering, Hindawi Publishing. He is also lead editor for the journal's special issue on iterative processing. Dr. Schlegel served as technical program chair of the IEEE Information Theory Workshop 2001, the IEEE International Symposium on Information Theory (ISIT'05) 2005, and as general chair of the 2005 IEEE Communication Theory Workshop (CTW'05), and the 2013 IEEE Conference on Wireless On-Demand Network Systems and Services (WONS'13).
Dr. Schlegel has published over 60 technical journal papers and received research grants for over 1 Million US$ from the National Science Foundation, the Army Research Office, the State of Utah, and private industry, notably L3 Communications in Salt Lake City, Utah, and more than 10 Million Can$ from iCORE, NSERC, the Canadian Foundation for Infrastructure (CFI), ASRA, the Canada Research Chair (CRC) program, and national and international industry. His work with industry has resulted in eight patents in the area of spread spectrum communication, error control coding, and digital and analog implementations.
