On March 27, 2019 at 11:00 AM, Dr. Gottfried Ungerböck will be giving a talk in the LNT Seminar room N2408 about "Guidance from information theory – an engineering perspective".

Guidance from information theory – an engineering perspective

Dr. Gottfried Ungerböck

Technical Director for the Communication Business Line


The talk is a repeat of the Shannon Lecture given at ISIT2018 on June 20, 2018, in Vail, USA. It reflects on some of the author's encounters with information theory in his application-oriented engineering career. The focus will be on (1) How Trellis Coded Modulation (TCM) came about, (2) The role of information theory in the development of 10GBASE-T, the IEEE 802.3 standard for 10 Gbit/s transmission over unshielded twisted-pair copper wires, and (3) Remarks on Faster-than-Nyquist (FTN) signaling.


Gottfried Ungerböck received an electrical engineering degree (with emphasis on telecommunications) from the Vienna University of Technology in 1964, and a doctorate from the ETH Zurich in 1970. He joined IBM Austria as a systems engineer in 1965, and the IBM Zurich Research Laboratory in 1967. At Zurich he worked on digital signal processing and switching systems, communications and information theory. He joined Broadcom in 1998 as Technical Director for the Communication Business Line.

Among many contributions to the theory of data transmission, Ungerböck invented trellis coded modulation. He is the 2018 Shannon Lecturer of the IEEE Information Theory Society.
