Polar Coded Modulation: A Tutorial

Zeit: Thu 19.5.2016, 18:00, 60 Minuten
Ort: JKU, Kepler Building, K 034D


The presentation starts with an introduction to coded modulation using the Multi- Level Construction (MLC). This concept is generalized by the definition of so called "sequential binary partitions". It is shown that Polar Codes, introduced by E. Arikan in 2007, and MLC are special cases of sequential binary partitions and concatenations of them. This leads to a new and rather simple proof of the capacity achieving property of Polar Codes. The derived framework allows for a joint description and optimization of both, binary polar coding and 2^m-ary digital pulse-amplitude modulation (PAM) schemes such as MLC and bit-interleaved coded modulation (BICM). The conceptual equivalence of polar coding and multilevel coding is covered in detail. Based on an alternative characterization of the channel polarization phenomenon, rules for the optimum choice of the labeling in coded modulation schemes employing polar codes are developed. Finally, simulation results and comparisons regarding the error performance of the proposed schemes on the AWGN channel are presented.


Johannes Huber received the Dipl.-Ing. degree in electrical engineering from the Technische Universität München, Munich, Germany in 1977. From 1977 to 1982 he was research assistant at the Lehrstuhl für Nachrichtentechnik of the Universität der Bundeswehr München, Munich, from which he received the Dr.-Ing. degree with a thesis on coding for channels with memory. Since autumn 1991, he is Professor at the Friedrich-Alexander-University Erlangen- Nuremberg, Germany. His research interests are information and coding theory, modulation schemes, algorithms for signal detection and adaptive equalization for channels with severe intersymbol interference, signalling, detection and equalization or multiple-input multiple-output (MIMO) channels and concatenated coding together with iterative decoding.<br><br> Johannes Huber is Fellow of the IEEE. He was a member of the board of governors of the IEEE Information Theory Society from January 1999 to December 2001 and again from January 2004 to December 2006. In 2008 he was appointed a corresponding fellow of the Royal Society of Edinburgh. Since 2009 Johannes Huber is an ordinary fellow of the Bavarian Academy of Sciences and Humanities.
