About the SnT

The Interdisciplinary Centre for Security, Reliability and Trust (SnT) invites applications from highly motivated PhD candidates in the general area of 6G communications. SnT carries out interdisciplinary research in secure, reliable and trustworthy ICT systems and services, often in collaboration with industrial, governmental or international partners. For further information, you may refer to www.

The research group focuses on wireless/satellite communications and networking and is headed by Prof. Symeon Chatzinotas. The research areas focus on the formulation, modelling, design, and analysis of future 5G and beyond communication networks that are capable of supporting new services in a cost- efficient manner. Use cases of interest include IoT verticals, unmanned aerial vehicles, integrated satellite-space-terrestrial networks, quantum communications and key distribution, spectrum management and coexistence, tactile Internet, and autonomous transportation. As far as technical enablers are concerned, we leverage expertise on massive MIMO cell-free communications, smart-radio environments through the use of intelligent surfaces, machine-type and ultra-reliable and low-latency communications, edge computing and caching, RAN slicing, and network softwarization and visualization. Finally, due to the large-scale nature, complexity, and heterogeneity of 5G and beyond networks, for their analysis and optimization we use tools such as artificial intelligence/machine learning, graph theory and graph-signal processing, and convex/non-convex optimization. Furthermore, our activities are experimentally driven and supported by the SDR CommLab, the S DN Lab, the 6G-Space Lab, our SW Simulators, and our OTA Facilties.

The successful candidate will work under the academic supervision of Prof. Björn Ottersten and Prof. Symeon Chatzinotas and join a strong and motivated research team.

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 Profile

Qualification: The candidate should possess an M.Sc./M.Eng. Degree in Telecommunication Engineering, signal processing, or a closely related field in Electronic, Electrical and Computer Engineering.

Experience: The ideal candidate should have a strong background in signal theory and digital communications, substantiated by relevant coursework/assignments. In addition, a background and interest in a number of the following areas is required:

  • Wireless and mobile communications. Background on either satellite or millimeter wave/THz communications is considered a plus.
  • Multiple-antenna transmission and reception methods in fading channels. Topics of interest are: massive-MIMO, cell-free massive MIMO, hybrid analog-digital beamforming, distributed antenna systems.
  • Digital signal processing.
  • Joint source-channel coding and decoding.
  • Detection and estimation theory.
  • Compressive sensing.
  • Edge computing and caching.
  • Energy harvesting, SWIPT, backscatter communications, and reconfigurable intelligent surfaces.
  • Software defined networking, network virtualization, and network slicing for wireless networks.
  • Resource allocation and optimization of communication networks.
  • Antenna theory.
  • RF and microwave engineering. Hands-on experience with RF electronics is a plus
  • Quantum communications.
  • Fiber optics or free-space optical communications.
  • Mathematical Tools: The candidate should have knowledge in a number of the following tools used for the analysis and optimization of communication networks.

  • Convex/non-convex optimization
  • Machine learning: supervised, unsupervised, and reinforcement learning. Knowledge of federated learning is considered a plus
  • Graph theory and graph signal processing
  • Random matrix theory
  • Statistical signal processing
  • Stochastic geometry
  • Software tools: Good programming skills in a number of widely used software tools, such as Matlab, Python, C/C++, CST/HFSS, is required.
