Joachim Hagenauer

Joachim Hagenauer ( born July 29, 1941 in Fürth ) is a German engineer who deals with telecommunications.

Hagenauer went in Fürth at the high school, earned his college degree in engineering in 1963 at the Georg -Simon- Ohm University in Nuremberg and his Diploma Engineer in Electrical Engineering in 1968 at the Technical University of Darmstadt, where he was in 1974 a PhD (error during scanning and restoring of band-limited signals ). As a post - graduate student, he was 1975/76 at the 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 the Director of The Institute for Communications Technology and also a professor at the Technical University of Munich, where he was a full professor since 1993 and Director of the Institute for Communications Technology. 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 in the enforcement of tough decisions in the decoding process and contributed to the development of turbo codes and based on the development of fast VLSI decoder ( in the range of Gigabits was per second). Then based techniques have been applied for example in digital radios, mobile phones, and satellite communications.

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

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

In 1996 he received the EH Armstrong Award from the IEEE Communications Society, 2004, the Heinz -Maier -Leibnitz medal and he was awarded the Erich Regener Prize and the Otto Lilienthal price. In 2003 he received the IEEE Alexander Graham Bell Award. He is a member of the Bavarian Academy of Sciences (2002) and Fellow of the IEEE (1992). In 2006 he became an honorary doctorate from the University of Erlangen- Nuremberg and the ring of honor to VDE.
