Dimitrios Efstathiou

Dr. Dimitrios Efstathiou serves as a Professor at the Department of Informatics, Computer and Telecommunications Engineering of the International Hellenic University (Serres Campus), bringing over 25 years of expertise in telecommunications systems with emphasis on baseband/intermediate frequency design. His industrial tenure includes critical roles at Nokia Mobile Phones and Analog Devices where he pioneered satellite receiver and base station technologies.

His educational foundation includes a B.E. in Electrical Engineering from the University of Patras (1989), M.Sc. in Digital Electronics (1991), and Ph.D. in Digital Communication Systems (1996), all from King's College London.

Efstathiou's research spans digital telecommunications theory, 4G/5G/6G systems, software-defined radio, IoT security, and physical layer countermeasures against jamming. His work addresses fundamental challenges in signal integrity, network efficiency, and wireless security through innovative algorithm design for timing circuits and digital PLLs. Recent publications demonstrate sustained leadership in WBAN standards and OFDM security enhancement.

His 50+ publications reveal evolving expertise from early software radio implementations to contemporary physical layer security frameworks, with consistent focus on practical baseband solutions for multi-carrier systems across 3G to 6G generations.

He has supervised 71 bachelor theses and numerous graduate projects while maintaining active industry collaboration. His IEEE leadership includes Chairing the Vehicular Technology and Aerospace Electronic Systems Joint Greece Chapter (2012-2020) and serving as Senior Member since 2006.
