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 transeivers. My current research is on the wireless positioning problem (together with Mohammad Gholami and Mats Rydström), medium access for sensor networks (joint work with Arash T. Toyserkani and Arne Svensson), and on vehicular communication for traffic safety applications (with Katrin Bilstrup, Elisabeth Uhlemann [Högskolan i Halmstad], and Stylianos Papanastasiou).

My CV is available here in pdf-format.
