Abstract

As the late Bruce Lee famously said, ‘Be water, my friend,’ emphasizing the power of adaptability in combat. On a broader scale, this philosophy resonates deeply with the ongoing advancements in reconfigurable antennas, which offer unparalleled flexibility to enhance wireless communications. In recent years, a groundbreaking concept known as the Fluid Antenna System (FAS) has emerged, pushing the boundaries of reconfigurable antenna technology. FAS introduces unprecedented adaptability in both shape and position, not only adding a new degree of freedom to the physical layer but also unlocking high-resolution signal access in the spatial domain—a capability that revolutionizes multiple access techniques. This talk explores how FAS transforms spatial-domain multiple access. Specifically, Fluid Antenna Multiple Access (FAMA) enables Spatial Division Multiple Access (SDMA) without requiring channel state information (CSI) at the transmitter for precoding or complex detection schemes such as successive interference cancellation. By simplifying system design and reducing the reliance on base stations for CSI acquisition and precoding, FAMA significantly enhances efficiency at the receiver side. We will conclude by demonstrating how this innovative approach paves the way for smarter, more adaptable wireless communication networks, making next-generation systems more efficient and resilient.

Bio

(Kit) Kai-Kit Wong was born in Hong Kong and received the BEng, the MPhil, and the PhD degrees, all in Electrical and Electronic Engineering, from the Hong Kong University of Science and Technology, Hong Kong, in 1996, 1998, and 2001, respectively. He is Chair Professor of Wireless Communications at the Department of Electronic and Electrical Engineering, University College London after taking appointments at University of Hong Kong and University of Hull and visiting positions at Lucent Technologies, Bell Labs and Stanford University. His current research centers around 6G and beyond mobile communications. He is one of the early researchers who proposed multiuser MIMO. His first paper on multiuser MIMO was published in WCNC 2000 which appeared to be the first ever research paper on this topic. He is Fellow of IEEE and IET. He served as the Editor-in-Chief for IEEE Wireless Communications Letters between 2020 and 2023.
