Joachim Speidel

Joachim Speidel (born November 17, 1947 in Plüderhausen near Stuttgart ) is a German engineer and professor of communications . He is one of the pioneers who helped shape the field of telecommunications in teaching and application-oriented research.

Life

After completing his university entrance qualification and a two-year internship at Deutsche Telekom , Joachim Speidel began studying electrical engineering with a focus on theoretical communications technology at the University of Stuttgart in 1969 , where he passed the diploma examination with distinction in 1974 .

He then worked at the Institute for Network and System Theory at the University of Stuttgart with Ernst Lüder as a scientific assistant in the field of digital signal processing and received his doctorate in 1980 on "Fast automatic and recursive equalizers and pulse shapers for data transmission" with distinction.

He is with the teacher Margrit Speidel , geb. Bartok, married, and the couple have three grown sons.

Industrial activity

This was followed by twelve years of industrial activity at Philips Kommunikation Industrie AG in Nuremberg in various positions: as an engineer for research and development, as head of laboratories and as director of a product division for television transmission and subscriber access networks .

During this time, he and his team also made significant contributions to the international standardization of video coding processes and realized the first coder for moving images with bit rates of up to 2 Mbit / s according to the ITU standard H.261 as a product on which the current MPEG standards and H.264 .

Act as a professor

In 1992 he was appointed to succeed Wolfgang Kaiser as professor at the University of Stuttgart and head of the Institute for Information Transmission (INÜ). There he deals with the broad field of message transmission across all network technologies, such as electrical, optical and cellular networks. The focus is on coding and modulation as well as multiple-input-multiple-output systems ( MIMO ).

Areas of application for his research work are in-house and factory networks with wired transmission, data transmission over power supply lines, optical data transmission over plastic fibers for multimedia applications in vehicles, and very fast optical transmission over glass fibers with multi-gigabits per second for the information superhighway.

He is also particularly concerned with the challenges of modern broadband mobile communications . These include powerful transmission, reception and modulation processes, algorithms for estimating the statistical channel parameters and systems with multiple-input-multiple-output (MIMO) , which play an important role when several antennas are used at the transmitter and receiver.

Numerous scientific publications have emerged from the theoretical and application-related research work of Joachim Speidel.

Joachim Speidel was Dean of the Faculty of Electrical Engineering and Information Technology from 1996 to 1998 , his successor was the automation and software engineer Peter Göhner , who was then Vice-Rector. From 2010 to 2013 Speidel was again dean of the now enlarged faculty of computer science, electrical engineering and information technology as well as a member of the extended rectorate of the University of Stuttgart (rector: Wolfram Ressel ). As a two-time dean, he has further developed and profiled the faculty in the fields of electrical engineering , information technology and computer science at the University of Stuttgart.

When Speidel reached the age limit, he switched to a research professorship at the Institute for News Transmission. As a pioneer in communication technology, he does not see this subject as closed, and therefore he continues to work on the scientific preparation for future solutions in contact with industrial and research partners. He and his team rely on interdisciplinary scientific collaborations, in particular with application-oriented fields such as industrial communication technology (Leipzig, professorships Werner Kriesel and Tilo Heimbold ) and circuit technology (Rostock, professorship Helmut Beikirch ). Stephan ten Brink was appointed as his successor on the chair and in the management of the Institute for Telecommunications .
