Klaus Witrisal received the Dipl.-Ing. degree in electrical engineering from Graz University of Technology in 1997, the Ph.D. degree (cum laude) from Delft University of Technology, The Netherlands, in 2002, and the Venia Docendi (Habilitation) from Graz University of Technology in 2009 in "Wireless Communications". From 1997 till 2001, he was a Research Engineer at Delft University of Technology, where he was key researcher in a collaborative research project with Korea Telecom in the field of OFDM air-interface design. This research was the basis for his Ph.D. thesis. From Jan.--Oct. 2002, he was a Project Leader with AVL in Graz, Austria, working on advanced diagnostics tools for the automotive industries. Since Nov. 2002, Dr. Witrisal is with the Signal Processing and Speech Communication Laboratory (SPSC) of Graz University of Technology, where he runs a number of research projects in the area of ultra-wideband (UWB) communications and positioning. He has been involved as a project leader for TU Graz in the sixth-framework project EUROPCOM, which has successfully demonstrated a UWB based ad-hoc network for emergency personal, providing indoor localization at high-accuracy. He has been supervising several Ph.D. projects, with funding from various sources, the Christian Doppler Gesellschaft, Österreichische Forschungsförderungs Gesellschaft (FFG) (within the program lines Bridge and FIT-IT), Land Steiermark, and Österreichischer Austauschdienst (ÖAD). He finalized his Habilitation Thesis on Noncoherent UWB Transceivers in 2008, whose introduction has been published in the IEEE Signal Processing Magazine in July 2009. Dr. Witrisal and his students have received best paper awards at international conferences (IEEE Intern. Symp. on Personal, Indoor, and Mobile Radio Communications (PIMRC) in 1998 and IEEE International Conference on UWB Systems (ICU) in 2005), the GIT award for a graduation thesis (for Christoph Steiner in 2004), and a nomination for the KIvI Telecom Award in the Netherlands, in 1999.
