The 6G-REFERENCE project participated in the 59th Asilomar Conference on Signals, Systems, and Computers, held from 26 to 29 October 2025 at the Asilomar Conference Grounds in Pacific Grove, California, USA. Recognised as one of the leading international forums in the field, the conference gathered around 1,600 participants from academia and industry to discuss the latest advances in signal processing, communication systems, and computing technologies.
Representing 6G-REFERENCE, António Barros, PhD Candidate at ETH Zürich, one of our consortium partners, presented their latest work through a poster entitled “Multipath and Interference Resilient ToA Estimation”, also co-authored by Christoph Studer, Professor in the same organisation, on 27 October 2025.
The poster addresses one of the fundamental challenges in next-generation wireless systems: achieving highly accurate time-of-arrival (ToA) estimation in complex propagation environments characterised by strong interference and severe multipath. Such conditions are common in dense urban or industrial settings, where signals can suffer from reflections and jamming.
ETH Zürich’s work introduces a novel algorithm that jointly enhances signal detectability under interference and mitigates multipath-induced bias, thereby enabling super-resolution ToA estimation with millisecond-level processing times. These advances are crucial for enabling precise positioning and over-the-air time synchronisation, both of which are key technologies for the future 6G ecosystem.
“The 59th Asilomar Conference on Signals, Systems, and Computers was an excellent opportunity to present our latest work on accurate and computationally efficient ToA estimation, which attracted strong interest from both industry and academia. It also provided a great forum to exchange ideas with fellow researchers and explore the latest advances in wireless communications, spanning topics such as machine learning for communications, array signal processing, and antenna array design. Our work represents a significant contribution to signal processing for communications and serves as a key enabler for future over-the-air time synchronisation protocols, one of the main goals of the 6G-REFERENCE project.” – António Barros, PhD Candidate at ETH Zürich.
The participation of ETH Zürich at Asilomar 2025 underscores the 6G-REFERENCE consortium’s commitment to driving innovation in signal processing and communication technologies. The outcomes of this research contribute directly to the project’s mission of designing robust, synchronised, and interference-resilient solutions that will underpin the next generation of 6G networks.

The Asilomar Conference on Signals, Systems, and Computers is a yearly conference held on the Asilomar Grounds in Pacific Grove, CA, USA. The IEEE Signal Processing Society is a technical co-sponsor. It provides a forum for presenting recent and novel work in various areas of theoretical and applied signal processing.
General areas of interest to the forum include:
- Architectures & Implementation
- Array Signal Processing
- Biomedical Signal & Image Processing
- Communication Systems
- MIMO Communications & Signal Processing
- Networks & Graphs
- Signal Processing & Adaptive Systems
- Machine Learning & Data Analytics
- Speech, Image & Video Processing
Recent meetings have presented a wide array of work ranging from results in MIMO communications, array processing, low dimensional signal models, blind source separation, tensor models, stochastic optimization, online and distributed learning, and signal processing over graphs to applications of signal processing in control, wireless communications, financial engineering, smart grids, biological systems, medical imaging, and big data.
