The University of Luxembourg is seeking to hire a highly motivated and outstanding researcher in the area of machine learning optimization for physical layer applied to satellite communications in its Interdisciplinary Centre of Security and Trust (SnT), within the Signal Processing and Communications (SigCom) research group, led by Prof. Symeon Chatzinotas.
SnT carries out interdisciplinary research in secure, reliable and trustworthy ICT (Information and Communication Technologies) systems and services, often in collaboration with governmental, industrial and international partners. SnT is active in several national projects funded by National Research Fund (FNR) and local industries, and international research projects funded by the EU FP7 programme, H2020 programme, and the European Space Agency (ESA). For further information, you may check: www.securityandtrust.lu
The SigCom research group carries out research activities in the areas of signal processing for wireless communication systems, including satellite and 5G/6G communications. It is expanding its research activities to explore several emerging use cases of next-generation wireless communications systems.

We’re 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…
This is a fully funded postdoc position for 2 years within an ESA project (TANNDEM-Demodulator based on Artificial Neural Network). Therefore, the objectives of the postdoc are defined in accordance with the TANNDEM directions toward reducing complexity and resources in the receiver, as well as increasing the performance for integrating satellites on 5G networks. More precisely, the work aims at designing artificial neural networks for different functionalities in the physical layer.
The successful candidate will work under the academic supervision of Dr. Jorge Querol (University of Luxembourg) and join a strong and motivated research team led by Prof. Symeon Chatzinotas.
The successful candidates are expected to perform the following tasks:
- Optimize 5G New Radio (NR) with waveform based on orthogonal frequency-division multiplexing (OFDM) and its evolution for satellite communication (Satcom) applications
- Design machine learning models to reduce the computational complexity and power consumption of several physical layer processing blocks of the receiver, such as decoding, channel estimation, and demodulation
- Ensure the ML models reduce the complexity while maintaining satisfactory performance in terms of throughput and bit-error-rate
- Identify the most suitable metrics to evaluate the machine learning models considering the system performance
- Implementing and developing a software and/or hardware testing environment to compare and evaluate the proposed techniques and architectures
- Disseminating results through scientific publications and conferences
- Contribute to the different research projects, either coordinating technical contributions and/or preparing project deliverables
- Preparing new research proposals to attract industrial, national, and European projects
- Eventually providing assistance in the supervision of PhD students
Your Profile…
- A PhD degree in Telecommunication Engineering, or Electrical Engineering or Computer Science/engineering with a focus on wireless communications and AI/ML tools and methods
- Experience in signal processing for wireless communications algorithms. Especially strong knowledge of the physical layer (tasks such as decoding, demodulation, and estimation)
- Background in optimization theory
- Experience using machine learning to solve/improve physical layer processing tasks, especially decoding
- Practical experience in using FPGA accelerators such as Versal to train/evaluate AI/ML models
- Sound publication track record in relevant international conferences and top journals in the following research areas (at least one IEEE Transaction publication is mandatory)
- Strong programming skills in MATLAB, Python/TensorFlow/Sionna. Others, like C/C++, are a plus but not mandatory
- International experience is desirable
- Experience working with industrial 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
In Short…
- Contract Type: Fixed Term Contract 24 Month (which may be extended up to five years)
- Work Hours: Full Time 40.0 Hours per Week
- Location: Kirchberg
- Job Reference: UOL05980
The yearly gross salary for every Postdoctoral Researcher at the UL is EUR 81072 (full time)
How to apply…
Applications should include:
- Curriculum Vitae, including:
- Contact address
- For each degree received or currently enrolled in, provide the degree, insitution nam, institution city and country, and start/end date (or expected date) of graduation. Include the title and short summary of your PhD Thesis and supervisor name (and Bachelor / Master Thesis if you did one)
