In this interview, Mamoun Guenach from IMEC and Florent Torres from Ericsson outline the progress and objectives ofT6.1, which focuses on validating AI-based signal processing and theoretical models developed in earlier stages of the project.
These validations aim to ensure robust and trustworthy wireless communications for a wider range of frequency bands such as sub-6 GHz, sub-10 GHz, and sub-terahertz.
A key aspect of T6.1 is a mixed approach combining software components from the link-level simulators (PHY models) with real hardware components, so-called “hardware-in-the-loop” validation. In fact, there are three proof-of-concept demonstrations:
- Sub-6 GHz Proof of Concept: Led by Ericsson, this focuses on RF device identification using radio frequency fingerprints. Using 5G signals and neural networks, the team achieved over 80% identification accuracy for devices from the same manufacturer, with some early results exceeding 90%. The team is also addressing cybersecurity challenges, such as impersonation attacks using replayed RF signals. In closed-set scenarios, high accuracy has been achieved in authenticating even identical devices. In open-set conditions, where attackers are not part of the training data, preliminary results are promising, though more work is ongoing.
- Sub-10 GHz Proof of Concept: Conducted by NXP and targeting fingerprinting accuracy in the presence of manufacturing variations, particularly in Doherty power amplifiers used in 5G base stations. Early simulation datasets have been shared with Ericsson for validation, highlighting strong partner collaboration.
- Sub-terahertz Proof of Concept: Managed by IMEC, this work assesses how residual RF non-idealities after mitigation impact the D-band radio link reliability and security. This is particularly crucial to control the beam-steering to enhance D-band link security. A link-level simulator has been developed and integrated with custom IC designs (developed outside the COREnext project) to demonstrate advanced features such as beam steering.
Overall, T6.1 demonstrates strong collaboration and promising technical results, forming a solid foundation for future developments within the project.
