Research Associate (Postdoc) in Signal Processing Based Solutions for THz Ultra-Massive MIMO Systems with RISs for 6G

Als Favorit speichern

The University of Luxembourg is seeking to hire a highly motivated and an outstanding researcher in the area of signal processing-based solutions for 6G wireless systems for its Interdisciplinary Centre of Security and Trust (SnT), within the Signal Processing and Communications (SigCom) research group headed by Prof. Symeon Chatzinotas. The selected candidate will work on a recently awarded Horizon SNS project on 6G networks.

SnT is a leading international research and innovation centre in secure, reliable and trustworthy ICT systems and services. We play an instrumental role in Luxembourg by fueling innovation through research partnerships with industry, boosting R&D investments leading to economic growth, and attracting highly qualified talent.

The SigCom research group works across the entire spectrum of blue-sky research and applied research to conceive and demonstrate future communication paradigms. Researchers with an interest in terrestrial and non-terrestrial communication systems, will find a large and vibrant team of over 70 members fostering a collaborative atmosphere. SIGCOM’s state-of-the art facilities include 4 physical laboratories: the Software Defined Networking Lab, the Communications Lab, the 5G Space Communication Lab, in addition to the SATCOM Lab of the Interdisciplinary Space Master. The group is also the recipient of numerous awards, such as the European Association for Signal Processing (EURASIP) Group Technical Achievement Award, the IEEE Communications Society Distinguished Contributions to Satellite Communications Award, as well as 4 European Research Council grants.

We are looking for people driven by excellence, excited about innovation, and looking to make a difference. If this sounds like you, you’ve come to the right place!

Your Role...

The successful candidate is expected to perform the following tasks:

  • Analyzing and investigating efficient signal processing methods for ultra-massive multiple-input multiple-output (MIMO) networks with reconfigurable intelligent surfaces (RISs) over THz wireless channels
  • Developing low-complexity channel estimation/prediction, beam training/tracking, hybrid (analog/digital and active/passive) precoding, and resource management schemes for both co-located and distributed THz wireless networks
  • Investigating the spectral and energy efficiency performance of 6G networks with various types of RISs (active, passive, reflective, and transmissive), and analyze the resultant complexity/performance trade-offs
  • Investigating efficient artificial intelligence (AI)-based solutions to tackle the main challenges in RIS-aided ultra-massive MIMO systems over THz channels
  • Disseminating results through scientific publications and conferences
  • The candidate is expected to actively contribute to the different research projects at SnT, either coordinating technical contribution and/or preparing project deliverables
  • Preparing new research proposals to attract industrial, national, and European projects
  • Providing assistance in the supervision of PhD students

Your Profile...

  • A PhD degree in Telecommunication Engineering, Electrical Engineering or Computer Science/engineering with a focus on wireless communications
  • International postdoc experience is desirable
  • Sound publication track record in relevant international conferences and top journals in the following research areas (at least one IEEE Transaction publication is mandatory):
    • Multi-antenna signal processing, e.g. beamforming/precoding
    • Radio resource management, e.g. power/bandwidth allocation, interference suppression, user scheduling
    • RIS-aided networks and/or THz communications
  • Experience with a number of optimization tools and typical convexification strategies
  • Experience with machine learning and artificial intelligence is highly desirable
  • Strong programming skills in MATLAB. Python, JULIA and C++ are desirable but not mandatory
  • Experience of working with industrial projects or public funded research projects is highly desirable
  • Highly committed, excellent team-worker, and strong critical thinking skills
  • Excellent written and verbal communication skills in English

Here’s what awaits you at SnT...

  • Exciting infrastructures and unique labs. At SnT’s two campuses, our researchers can take a walk on the moon at the LunaLab, build a nanosatellite, or help make autonomous vehicles even better
  • The right place for IMPACT. SnT researchers engage in demand-driven projects. Through our Partnership Programme, we work on projects with more than 55 industry partners
  • Be part of a multicultural family. At SnT we have more than 60 nationalities. Throughout the year, we organise team-building events, networking activities and more
