George Ntavazlis Katsaros

George Ntavazlis Katsaros is a Research Fellow at the Institute for Communication Systems, University of Surrey, and affiliated with the 5G/6G Innovation Centre. His research project, Massively Parallel Non-Linear Processing Architectures for 6G Communications, focuses on architectural and algorithmic design of real-time, power-efficient MIMO PHY for future wireless systems and Open RAN, supervised by Konstantinos Nikitopoulos.

Research Interests: Katsaros specializes in 6G wireless technologies, with emphasis on non-linear signal processing, Open RAN frameworks, and energy-efficient MIMO systems. His work bridges hardware-aware algorithm design and practical implementation challenges in 5G/6G networks, targeting scalability and real-time operability.

Publication Trends: Recent articles (2022–2023) explore non-linear processing’s role in enhancing MU-MIMO throughput, reducing base-station hardware requirements, and mitigating power consumption in software-based 5G PHY layers. Key themes include Open RAN compliance, over-the-air validation, and carbon footprint optimization.

Affiliations: He contributes to the 5G/6G Innovation Centre, a leading research hub advancing Open RAN standards and energy-aware PHY processing architectures.
