Abstract: In this talk, the physical layer design aspects of secure wireless communication systems are introduced. An overview is provided to highlight the fundamental differences between the civilian and military communication systems. Subsequently, the key building blocks of the physical layer in wireless communication systems are examined in detail. Through concrete examples, it is demonstrated how these design methodologies support a broad spectrum of application scenarios—from ultra-reliable, low-data-rate systems operating in critical environments to high-throughput data links—spanning the full frequency range from 30 MHz to 30 GHz across all scenarios. Finally, ongoing research efforts are briefly discussed, with a focus on integrated sensing and communications, showcasing how emerging 5G and 6G technologies are being tailored for secure, tactical communication systems.
Biography: Dr. Çağrı Göken received his B.S. and M.S. degrees from Bilkent University and his M.A. from Princeton University, all in Electrical Engineering. He earned his Ph.D. from Bilkent University in 2019. Since 2016, he has been with ASELSAN Inc., where he leads a team focused on tactical waveform and physical layer design for secure wireless communication systems.
His work includes the design of field proven anti-jam communication systems, such as narrowband and wideband ad-hoc networks, tactical data links, and high-capacity MIMO systems. He has also led projects on 5G Layer 1 algorithm development and integrated sensing and communications (ISAC), with a focus on adapting 5G/6G technologies for mission-critical defense applications. He has published in IEEE journals and conferences and has previously taught EEE 432/530 Advanced Digital Communications course at Bilkent University.
