Fluid Antenna System-Enabled Mitigation of Asynchronous Reception in Cell-Free Massive MIMO Systems
Jun Qian, Zan Li, Junhui Rao +2
Practical distributed deployments inherently suffer from asynchronous signal arrivals, which exacerbate multi-user interference and degrade system performance, especially for coher…
Covariance-Aware Detection for Single-RF MIMO-OFDM Systems
Tianrui Qiao, Jun Qian, Ross Murch
We propose the use of a covariance-aware detection method for single-radio-frequency (RF) multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) sy…
Fluid Antenna System Meets Low-Resolution ADCs in Energy-Efficient Cell-Free Massive MIMO
Jun Qian, Ross Murch, Khaled B. Letaief
This paper proposes a novel fluid antenna system (FAS)-enabled architecture to improve energy efficiency (EE) without sacrificing capacity. Specifically, we integrate FAS into cell…
Beyond Covariance: Generative Spatial Correlation Modeling and Channel Interpolation for Fluid Antenna Systems
Zhentian Zhang, Hao Jiang, Kai-Kit Wong +2
Fluid antenna systems (FAS) enable unprecedented spatial diversity within a compact form factor by flexibly switching among high-density antenna ports. To activate this capability,…
Phase-mismatched STAR-RIS with FAS-assisted RSMA Users
Farshad Rostami Ghadi, Kai-Kit Wong, Masoud Kaveh +4
This paper considers communication between a base station (BS) to two users, each from one side of a simultaneously transmitting-reflecting reconfigurable intelligent surface (STAR…
Downlink OFDM-FAMA in 5G-NR Systems
Hanjiang Hong, Kai-Kit Wong, Hao Xu +5
Fluid antenna multiple access (FAMA), enabled by the fluid antenna system (FAS), offers a new and straightforward solution to massive connectivity. Previous results on FAMA were pr…
