Joachim Hagenauer

Joachim Hagenauer (born July 29, 1941 in Fürth ) is a German engineer who deals with communications technology. He is a former professor of communications engineering at the Faculty of Electrical Engineering and Information Technology at the Technical University of Munich .

Hagenauer went to high school in Fürth, earned his technical college degree as an engineer in 1963 at the Georg-Simon-Ohm-Hochschule in Nuremberg and his graduate engineer in electrical engineering in 1968 at the TU Darmstadt , where he received his doctorate in 1974 ( errors in scanning and restoring band-limited signals ). As a post-graduate student he was 1975/76 at Thomas J. Watson Research Center of IBM , where he worked on error-correcting codes for magnetic storage. From 1977 he was at the DLR in Oberpfaffenhofen . From 1990 he was director of the Institute for Communication Technology and also professor at the Technical University of Munich , where he was full professor from 1993 and director of the Institute for Telecommunications. In 2006 he retired.

He was one of the developers of the soft bit technology (soft in / soft out principle), which avoided the loss of information when forcing hard decisions in the decoding process and contributed to the development of turbo codes and the basis for the development of fast VLSI decoders (in the gigabits per second) was. Techniques based on this have been used, for example, in digital radio, cell phones and satellite communications.

In 1986/87 he was an Otto Lilienthal Fellow at Bell Laboratories .

In 2001 he was President of the IEEE Information Theory Society.

In 1996 he received the EH Armstrong Award from the IEEE Communications Society, in 2004 the Heinz Maier Leibnitz Medal and he received the Erich Regener Prize and the Otto Lilienthal Prize. In 2003 he received the IEEE Alexander Graham Bell Award . He is a member of the Bavarian Academy of Sciences (2002) and a Fellow of the IEEE (1992). In 2006 he received an honorary doctorate from the University of Erlangen-Nuremberg and in the same year received the VDE Ring of Honor. In 2014 he received the VDE's ITG Science Award for Information and Communication Technology . Hagenauer is also a member of the German Academy of Science and Engineering (Acatech).
