The position is with the Division for Communication Systems which belongs to the Department of Signals and Systems. The division pursues advanced research in wireless and fiber optical communication links and systems. The researchers have participated in developing 3G (WCDMA) and took part in the first demonstration of communication via ultra-wideband (UWB) in Europe (in 2004). Currently, the division participates, among other things, in an EU project which develops the 4th generation wireless communication system and a European network of excellence in wireless communications. The open position is funded by the Swedish Research Council and deals with reliable packet transmission in ultra-wideband systems. This work will be performed in close cooperation with similar UWB research in the High Speed Wireless Communication center, which Lund University and Chalmers is about to start with funding from the Foundation of Strategic Research.
