Information, Communication and Imaging


The ICI group’s research focus is on wireless communications, information theory, signal processing and imaging.

The key application areas covered by the group’s research output lie primarily on 5G/6G, IoT and machine learning for communications; coding and information theoretic security; networking and edge computing; imaging and modelization.


Research areas

The ICI group’s research focus is on core topics on wireless communications, information theory, signal processing and MAC / network slicing, emerging imaging and modelling.

Current research topics are pertinent to IoT verticals (with emphasis on V2X and Smart factories) and lie primarily on the following domains:

Wireless communications, B5G and 6G / PHY aspects

resource allocation and optimization, low energy (green AI, energy harvesting), low latency (short packet comms, finite blocklength, effective capacity and delay QoS), localization for mmWave and subTHz, waveform design, ML for communications;

Coding and information theory

rate-adaptable codes for IoT, short blocklength code design, graph codes (e.g. LDPC), polar codes, lattice codes, interplay between information theory and game theory;

Networking slicing and caching, including

slicing, coding in Named Data Networks, layer 2 scheduling, energy efficient protocols, coexistence of heterogeneous services;

Security for wireless communications including

physical layer security (wiretap coding, covert communications, secret key generation), jamming and active attacks at RAN, cross-layer anomaly detection, physical unclonable functions, privacy, post-quantum cryptography (code and lattice based).

Imaging and modelling

recent research concerns Tomography and Emerging Imaging: new concepts, associated inverse problems and artificial intelligence (AI)-based approaches.
