报告简介

The Fluid Antenna System (FAS) represents a groundbreaking advancement in reconfigurable antenna technologies, offering unparalleled flexibility in both shape and positioning for wireless communications. While FAS is widely recognized for introducing a new degree of freedom to the physical layer, thereby enhancing performance across a range of wireless applications, a key question remains: How does FAS perform when integrated with Orthogonal Frequency Division Multiple Access (OFDM), the waveform used in 5G and beyond systems? It is clear that a position optimal for one frequency subcarrier may not be ideal for others, raising concerns about the effectiveness of FAS in OFDM systems. This talk aims to address these concerns by exploring how FAS can be seamlessly integrated with OFDM, presenting system-level simulation results in a 5G context. Our findings demonstrate significant performance improvements when FAS is used in OFDM systems.
