Wireless Communications Laboratory (WICL) was founded in September 2015 by Professor Bang Chul Jung in the Department of Electronics Engineering, Chungnam National University. In March 2025, Professor Bang Chul Jung and WICL officially relocated to the Department of Electrical and Computer Engineering at Ajou University.

We carry out advanced research on various cutting-edge technologies in wireless communications, statistical signal processing, machine learning, and information theory. In general, we apply mathematical tools such as linear algebra, mathematical analysis, statistics and probability theory, optimization theory, and information theory to analyze performances of the developed technologies. Our research interests include 6G mobile communications, physical-layer security, mmWave communications, analog/digital/hybrid beamforming, compressed sensing, wireless localization, military communication systems, radar signal processing, spectrum sharing techniques, statistical machine learning, sparse Bayesian learning, interference management, spectrum engineering, etc.

WICL is led by Prof. Bang Chul Jung, the recipient of the 5th IEEE Communication Society Asia-Pacific Outstanding Young Researcher Award in 2011, the KICS Haedong Young Scholar Award in 2015, the 29th KOFST Science and Technology Best Paper Award in 2019, and the Commendation Award from the Minister of Science and ICT in 2024. Prof. Jung served as an Associate Editor of the IEEE Vehicular Technology Magazine from 2020 to 2022 and is currently a Senior Editor of the same journal as well as an Associate Editor of the IEEE Open Journal of the Communication Society. He was also the TPC Chair of IEEE CCNC 2023 and now serves as the General Chair of IEEE CCNC 2025.
