A principal focus of our research is the development of technology components for 6G wireless networks. Specific topics include the design and optimization of distributed and massive MIMO for high-capacity coverage and low-latency wireless access; methods to support energy-neutral (passive) devices and augmented, virtual and extended reality over wireless; design of wireless networks to support distributed AI and machine learning applications; and implementation of signal processing systems.

Security, robustness and energy-efficiency of communication links and networks are additional topics of importance.

Our work uses tools from statistical signal processing, information and communication theory, machine learning, complex networks and optimization.

Research projects

Integrated Sensing and Communications (ISAC)

One of the most promising features that will be integral part of the next generation of wireless mobile networks, 6G, is the integration of sensing functionality.

Illustration RadioWeaves - The emerging physical-layer infrastructure for 6G wireless communications

RadioWeaves 鈥� physical-layer infrastructure for 6G wireless communication

RadioWeaves is an emerging physical-layer wireless access infrastructure, in which a fabric of distributed radio devices and computing resources serve as a massive distributed antenna array.

Energy-Efficient Digital Signal Processing

Energy efficiency in signal processing hardware is vital for several reasons, in particular to reduce the environmental impact, to increase stand-by times, to make batteries smaller and lighter, and to simplify the cooling of circuits.

Physical layer security and privacy (PLS)

Physical Layer Security is a security approach that operates directly on wireless signals, leveraging the unique characteristics of the propagation channel and hardware as sources of entropy to ensure confidentiality, integrity, and authentication.

Wireless Network Design for Decentralized Machine Learning

Wireless Communications for Distributed Intelligence

This project aims at establishing a general framework for the joint design of information processing and wireless resource allocation to achieve communication efficiency and reliability in decentralized Machine Learning systems.
