The following incomplete list provides examples for research projects performed by the Microwave Engineering Group of TU Wien during the last five years:
Ongoing projects:
- CDG Location: Christian Doppler Laboratory for Location-aware Electronic Systems (funded by Christian Doppler Gesellschaft)
Studying of various technologies and physical layer interfaces for indoor localization. - InterOp: Interoperability of Heterogenous Radio Systems (funded by EFRE Interreg V-A Austria Czech Republic)
Measurement, modeling, simulation/emulation of linear and nonlinear interference. - LIMAR: L-Band Interference Mitigation for an Aeronautical Receiver (funded by Austrian Research Promotion Agency FFG)
Investigation of robust receiver circuits and algorithms for LDACS-1 communication under strong in-band interference/blocking conditions. Simulation, optimization, and hardware verification of a joint HW/SW OFDM-receiver design. The project serves as the basis for one PhD thesis at TU Wien.
Finished projects:
- SES RSSI (direct funding from industrial partner)
Characterization of the antenna pattern of electronic shelf labels by coherent nearfield measurements. - Backscatter Localization (direct funding by industrial partner)
Development of a ΔRCS measurement system for evaluating backscatter localization performance at UHF, 2.45 GHz, and 5.8 GHz. - REFlex: RFID Real-Time Localization for Flexible Production Environments (funded by Austrian Research Promotion Agency FFG)
Investigation of UHF RFID ranging with unmodified tags. Includes RF design, signal processing, and FPGA-concept. Interdisciplinary research including studies of ethical implications. - TX4Green: PWM-based transmitter for green base-stations (funded by Vienna Science and Technology Fund WWTF)
Switched mode power amp¬lifiers with high efficiency.
