Currently he is head of the Department of Signals and Systems, Chalmers University of Technology, Gothenburg, Sweden, where he was appointed Professor in Communication Systems in April 1993. Before 1985 he held various teaching and research positions at the University of Lund. From April 1985 to July 1987, he was a Research Professor (Docent) at the Institute of Telecommunication Theory, University of Lund. In Aug. 1987, he joined the Airborne Electronics Division at Ericsson Radio Systems AB, Mölndal, Sweden. After a company reorganization in Jan. 1988, he became employed by Ericsson Radar Electronics AB, where he first was a member of the New Projects Group at the Airborne Electronics Division and then from Sept. 1990 to Dec. 1994 a member of the Mobile Telephone Systems Group at the Microwave Communications Division. His consulting company BOCOM, is involved in studies of error control methods, modulation and demodulation techniques, spread spectrum and CDMA systems, and computer simulation methods for communication systems. His current interest include channel coding and decoding, digital modulation methods, digital satellite systems, CDMA and spread spectrum system, and personal communication networks.

Prof. Svensson has published one book, three book chapters, 41 journal papers / letters, four editorials and more than 160 conference papers. In 1986, he was recognized with the IEEE Vehicular Technology Society Paper of the Year Award, and in 1984, he received the Young Scientists Award from the International Union of Radio Science, URSI. From 2007, he is member of the Proceedings of the IEEE Editorial Board. He was editor of the Wireless Communication Series of IEEE Journal of Selected Areas in Communications until 2002 and IEEE Transactions on Wireless Communications between 2003 and 2007. He was chief editor for a special issue on "Adaptive Modulation and Transmission in Wireless Systems" for the Proceedings of the IEEE which was published in Dec. 2007. He was guest editor of a special issues on “Ultra-wideband (UWB) Communication Systems - Technology and Applications” which was published in 2006 and a special issue on "Multicarrier Systems" which was published in 2008; both in EURASIP Journal on Wireless Communications and Networking. He was also guest editor of a special issue on COST289 research for Springer Journal on Wireless Personal Communications, which will appear in 2008. He has been involved in organising many conferences and sessions in topics related to wireless communications. He is a fellow of the IEEE, a member of IEEE Communications Society, IEEE Signal Processing Society, IEEE Information Theory Society, IEEE Vehicular Technology Society, the Swedish URSI committee (SNRV, Svenska Nationalkommitten för Radiovetenskap), and the council of NRS (the Nordic Radio Society). He was member of the executive board of the European network of excellence Newcom, member of the council of SER (Svenska Elektro- och Dataingenjörers Riksförening), director of studies in a national research school in Personal Computing and Communications,  chairman of the evaluation committee of the SIBED program at Vinnova, and president of the European Internation 4H Youth Exchange (IFYE) association.
