The is an international research university with a distinctly multilingual and interdisciplinary character.The at the University of Luxembourg is a leading international research and innovation centre in secure, reliable and trustworthy ICT systems and services.
We play an instrumental role in Europe by fueling innovation through research partnerships with industry, boosting R&D investments leading to economic growth, and attracting highly qualified talent. We look for researchers from diverse academic backgrounds to contribute to our projects in areas such as: Network Security, Information Assurance, Model-driven Security, Cloud Computing, Cryptography, Satellite Systems, Vehicular Networks, and ICT Services & Applications.The Signal Processing and Communications (SIGCOM) research group of SnT conducts research aimed at designing, emulating and testing new high-performance systems for the future of mobile and satellite communications. Fields of applications range from 5G/6G telecommunications to satellite-based internet connectivity. For details, you may refer to the following:In addition, SIGCOM hosts the following experimental facilities:
  • 6GSpaceLab: Real-world validation of advanced communication algorithms
  • CommLab: Real-time wireless testbeds for DSP in satellite and terrestrial systems
  • HybridNet Lab: Validation of large-scale autonomous and heterogeneous network orchestration
  • QCI Lab: Quantum communication and QKD research across all network layers
  • TelecomAI Lab: AI-based solutions for 5G/6G and satellite communications
  • CSAT Lab: Design, fabrication, and measurement of advanced antenna technologies
Your roleWe look for Doctoral Researchers from diverse academic backgrounds to contribute to our projects in the 4 strategic research areas of SIGCOM, namely: i) Radio frequency transceiver design; ii) Optical communications; iii) Quantum communications; iv) System-level design and optimization. The related domains and topics for each of these research areas that we would like to attract excellent researchers to work on are the following:Radio frequency transceiver design
