Abstract

In this lecture we will explore the impact of iterative processing on recent developments in error control coding and communications systems theory. This first part discusses the state of the art in iterative matrix inversion methods, and how they relate to iterative implementations of signal processing algorithms, such as the zero-forcing and minimum mean-square error filters. We then derive non-linear versions of these iterative processors, where soft-output error control decoders are included in the iteration process.
This leads to the need for new analysis methodologies, primarily based on density evolution, which we will briefly review. 

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.
