ToF sensors provide full range distance information at high frame-rates and thus have a significant impact onto current research in areas like online object recognition, collision prevention or scene reconstruction. However, ToF cameras like the photonic mixer device (PMD) still exhibit a number of challenges regarding static and dynamic effects, e.g. systematic distance errors and motion artefacts, respectively. Sensor calibration techniques reducing static system errors have been proposed and show promising results. However, current calibration techniques in general need a large set of reference data in order to determine the corresponding parameters for the calibration model. This paper introduces a new calibration approach which combines different demodulation techniques for the ToF- camera 's reference signal. Examples show, that the resulting combined demodulation technique yields improved distance values based on only two required reference data sets.}, language = {en} } @inproceedings{OPUS4-6272, title = {B-AMC — broadband aeronautical multi-carrier communications}, series = {Integrated Communications, Navigation and Surveillance Conference : [ICNS 2008] ; Bethesda, Md., 5 - 7 May 2008}, booktitle = {Integrated Communications, Navigation and Surveillance Conference : [ICNS 2008] ; Bethesda, Md., 5 - 7 May 2008}, organization = {Institute of Electrical and Electronics Engineers}, isbn = {978-1-4244-2303-3 ; 978-1-4244-2304-0}, pages = {1 -- 12}, year = {2008}, language = {en} } @inproceedings{SchnellBrandesGligorevicetal.2008, author = {Schnell, Michael and Brandes, Sinja and Gligorevic, Snjezana and Walter, M. and Rihacek, Christoph and Sajatovic, Miodrag and Haindl, Bernhard}, title = {Interference mitigation for broadband L-DACS}, series = {27th IEEE/AIAA Digital Avionics Systems Conference : DASC 2008 : 26-30 Oct. 2008, St. Paul, Minn.}, booktitle = {27th IEEE/AIAA Digital Avionics Systems Conference : DASC 2008 : 26-30 Oct. 2008, St. Paul, Minn.}, organization = {Institute of Electrical and Electronics Engineers}, isbn = {978-1-4244-2207-4 ; 978-1-4244-2208-1}, pages = {2B2-1 -- 2B2-12}, year = {2008}, language = {en} } @inproceedings{WangMensingGligorevicetal.2008, author = {Wang, W. and Mensing, C. and Gligorevic, Snjezana and Jost, T. and Dammann, A.}, title = {Short term statistical analysis of outdoor to indoor propagation channel for geolocations}, series = {Proceedings of the 13th International OFDM Workshop : (InOWo '08), Aug. 27./28. 2008, Hamburg : Session 3A: Systems concepts}, booktitle = {Proceedings of the 13th International OFDM Workshop : (InOWo '08), Aug. 27./28. 2008, Hamburg : Session 3A: Systems concepts}, organization = {International OFDM Workshop <13, 2008, Hamburg>}, pages = {85 -- 89}, year = {2008}, language = {en} } @inproceedings{EllerwegRitz2008, author = {Ellerweg, Roland and Ritz, Thomas}, title = {Tool supported requirements analysis for the user centered development of mobile enterprise software}, series = {Proceeding of Wireless Applications and Computing 2008 and Telecommunications, Networks and Systems 2008 : MCCSIS '08 ; IADIS Multi Conference on Computer Science and Information Systems ; 22 - 24 July 2008, Amsterdam, The Netherlands}, booktitle = {Proceeding of Wireless Applications and Computing 2008 and Telecommunications, Networks and Systems 2008 : MCCSIS '08 ; IADIS Multi Conference on Computer Science and Information Systems ; 22 - 24 July 2008, Amsterdam, The Netherlands}, editor = {Roth, J{\"o}rg}, publisher = {IADIS Press}, address = {[Lisboa]}, isbn = {978-972-8924-62-1}, pages = {160 -- 162}, year = {2008}, abstract = {A user centered development method has proved satisfactory for the development of mobile enterprise software.
