Doctoral Candidate (PhD student) in Modeling and Design of Mobile Networks Assisted by Reconfigurable Intelligent Surfaces

About the SnT

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.

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!

The Interdisciplinary Centre for Security, Reliability and Trust (SnT) invites applications from highly motivated PhD candidates in the area of channel estimation and resource allocation for emerging wireless networks within its Signal Processing and Communications (SIGCOM) research group. SnT carries out interdisciplinary research in secure, reliable and trustworthy ICT systems and services, often in collaboration with industrial, governmental or international partners.

The SIGCOM research group is headed by Prof. Symeon Chatzinotas and Prof. Björn Ottersten. The team focuses on signal processing for satellite/wireless communications/networking and radar applications. The research on communications focuses on the formulation, modelling, design, and analysis of future communication networks (beyond 5G) that are capable of supporting new services in a cost efficient manner. In the B5G domain, SIGCOM addresses large antenna systems, multiuser MIMO systems, Non orthogonal Multiple Access, radio resource management, mmWave beamforming, physical layer security, full duplex systems, wireless power transfer, software defined networking, network automation, and reconfigurable intelligent surfaces. In the satellite domain, SIGCOM addresses transceiver design, onboard processing, active antennas, multi-beam processing, optical communications, localization, spectrum monitoring and network performance optimization. The analysis is based on traditional statistical and optimization methods, as well as learning-assisted approaches for offline training and operational system monitoring/control. The communication activities are supported by CommLab, which exploits Software Defined Radios for fast prototyping and demonstration.

Your Role

This is a fully funded position for 3 years (extendable to an additional 4th year) within a large, national research project (RISOTTI – Reconfigurable Intelligent Surfaces fOr SmarT CiTIes). The objectives of the PhD project are defined in accordance with the project directions. More precisely, the PhD project aims at addressing channel modeling and characterization for mobile relays enhanced by reconfigurable intelligent surfaces (RIS) within the concept of Smart Cities. Here, one of the objectives will be to analyze various mobility profiles associated with the concept of Smart Cities. For each profile, various techniques of system modeling, such as Markov chains, machine learning, and analytical derivations, will be employed. Depending on the resulting channel models, various aspects of network design with multiple mobile RIS will be tackled via joint optimization.

The successful candidate will work under the academic supervision of Prof. Ottersten (University of Luxembourg) and join a strong and motivated research team of SnT.

The position holder will be required to perform the following tasks:

• Contribute to the national project “RISOTTI”


• Project website: https://urldefense.proofpoint.com/v2/url?u=https-3A__wwwfr.uni.lu_snt_re... rel="noopener noreferrer" target="_blank">RISOTTI
  


• Carry out research in the predefined areas


• Disseminate results through scientific publications


• Present results in well-known international conferences and workshops

Your Profile

Qualification: The candidate should possess a Master degree in Electronic Engineering, Computer Science or similar.
