Erik Ström

Professor, Head of Division, Communication Systems, Electrical engineering

Erik Ström is heading the Division of Communication Systems. His research involves Communication theory and Signal processing, specializing in coding and modulation, channel estimation, medium access, wireless positioning, and vehicular communications (V2V and V2I) for traffic safety and traffic efficiency applications (including automated driving). Erik pioneered the use of subspace methods for synchronization and channel estimation in CDMA systems, and has published over 150 conference and journal papers. He received Chalmers’ Pedagogic Prize, 1998 and Chalmers’ Supervisor of the Year Prize, 2009.

Once upon a time I was a student at the Royal Institute of Technology (KTH) where I received a Masters of Science (civilingenjör) in electrical engineering in 1990. I then spent four and a half wonderful years at the University of Florida in Gainesville, where I was a Ph.D. student and research associate at the High Speed Digital Architecture Lab under the supervision of Scott L. Miller and Fred Taylor. I learned to appreciate the delicate sport of American football and became an avid fan of Gator sports. I also managed to write and defend a Ph.D. thesis in 1994. 

With a fresh Ph.D. diploma, I returned to KTH and spent a year and a half with the Signal Processing group at the Dept. of Signals, Sensors, and Systems as a postdoc and later as an assistant professor (forskarassistent). Since June, 1996, I have been with Chalmers, and was promoted to full professor  in November of 2006. I am currently the head of the Division for Communication Systems and Information Theory. 

I have taught courses in signals and systems, information theory, communication theory, and detection theory (Yes, I like practical things, too; but, as Kurt Lewin said, nothing is as practical as a good theory).

I'm interested signal processing and communication theory in general. Specifically, I have been involved in research on channel estimation and synchronization for code-division multiple access (CDMA) systems, multiple access strategies for OFDM-based systems, bit-to-symbol mapping (also known as labeling) of two-dimensional signal constellations, and geographical positioning of radio transceivers.
My current research is on the wireless positioning and vehicular communication for traffic safety and traffic efficiency applications.

I am leading the competence area Sensors and Communication at the traffic safety center SAFER (hosted at Chalmers) and is a member of its extended management group.
