CAES & CSP Talk 1: Integrated Sensing and Communication - OFDM-based Approaches
Dear IEEE members and guests,
The IEEE Control, Aerospace and Electronic Systems (CAES) and IEEE Communication and Signal Processing (CSP) Chapters would like to invite you to two technical seminars on Friday, 18 August 2025. The first talk, titled "Integrated Sensing and Communication - OFDM-based Approaches," will start at 5:30 pm (Adelaide time). For more information on the second talk titled "Digital Camera Signal Processing — History, Recent Advances, Challenges, and Opportunities", please visit this talk page.
Abstract:
This talk explores the emerging paradigm of Integrated Sensing and Communication (ISAC), where base stations are designed to jointly perform wireless communication and environmental sensing. By sharing hardware and radio spectrum, ISAC improves spectral efficiency and enables advanced services in future wireless systems. We focus on orthogonal frequency division multiplexing (OFDM), the waveform widely adopted in 5G and beyond, and demonstrate how its structure can be leveraged for sensing. In particular, we show how reflected OFDM signals can be used to estimate delay and Doppler parameters for detecting and tracking moving objects. Conventional methods such as the periodogram are discussed, along with their limitations in resolution. To address these challenges, we introduce high-resolution techniques, e.g., subspace-based methods, which enable finer target discrimination in complex environments.

Prof Jinho Choi of University of Adelaide
Biography:
Jinho Choi was born in Seoul, Korea. He received B.E. (magna cum laude) degree in electronics engineering in 1989 from Sogang University, Seoul, and M.S.E. and Ph.D. degrees in electrical engineering from Korea Advanced Institute of Science and Technology (KAIST) in 1991 and 1994, respectively. He is with the School of Electrical and Mechanical Engineering, the University of Adelaide, Australia, as a Professor. His research interests include the Internet of Things (IoT), wireless communications, and statistical signal processing. He authored two books published by Cambridge University Press in 2006 and 2010 and one book by Wiley-IEEE in 2022. Prof. Choi received a number of best paper awards including the 1999 Best Paper Award for Signal Processing from EURASIP. He is a Fellow of the IEEE and has been on the list of World’s Top 2% Scientists by Stanford University since 2020. Currently, he is a Senior Editor of IEEE Wireless Communications Letters and an Associate Editor of IEEE Trans. Mobile Computing. He has also served as a Division Editor of Journal of Communications and Networks (JCN), an Associate Editor or Editor of other journals including IEEE Trans. Communications, IEEE Communications Letters, JCN, IEEE Trans. Vehicular Technology, and ETRI journal.
