Bistatic Integrated Sensing and Communications with Flexible Intelligent Metasurfaces
Iván Alexander Morales Sandoval, Thushar Venkataramanaiah, Kuranage Roche Rayan Ranasinghe +3
We propose a novel doubly-dispersive (DD) multiple-input multiple-output (MIMO) channel model incorporating flexible intelligent metasurfaces (FIMs), suitable for integrated sensin…
Baseband-Free Wideband MU-MIMO OFDM via Stacked Intelligent Metasurfaces
Zheao Li, Jiancheng An, Chau Yuen
This paper proposes a novel baseband-free wideband MU-MIMO OFDM transmitter architecture enabled by two cascaded stacked intelligent metasurfaces (SIMs). Unlike conventional wirele…
Task-Oriented Wave Processing with Stacked Intelligent Metasurfaces: Framework, Fusion, and Challenges
Qiao Qi, Qiyu Chen, Jiancheng An +4
The deep integration of diverse services in sixth-generation (6G) networks poses significant challenges to conventional task-agnostic channels, often resulting in performance confl…
DRL-Based Joint Beamforming and Surface Shape Optimization for Flexible Intelligent Metasurface-Aided ISAC Systems
Maoyuan Wang, Qian Zhang, Jiancheng An +3
Integrated sensing and communication (ISAC) unifies high-precision sensing and wireless data transmission. In this paper, we investigate the design of ISAC systems enabled by flexi…
Enhanced Channel Estimation for Flexible Intelligent Metasurface-Aided Communication Systems
Jinyue Jiang, Jiancheng An, Lu Gan +3
Flexible intelligent metasurface (FIM) has recently received considerable interest due to its advantage in realizing a better channel condition by dynamically morphing its surface…
Stacked Intelligent Metasurface-Enhanced Wideband Multiuser MIMO OFDM-IM Communications
Zheao Li, Jiancheng An, Chau Yuen
Stacked intelligent metasurfaces (SIM) enable fine-grained wave-domain signal processing, but their wideband deployment is impeded by two structural factors: (i) a single, quasi-st…
