Hybrid STAR-RIS Architecture for Joint Localization, Communication, and Power Transfer
Haoran Ni, Mohammadali Mohammadi, Xidong Mu +2
We propose a hybrid simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) architecture with dynamically switched active and passive elements to s…
Power-Efficient XL-MIMO Design for Mixed Near- and Far-Field SWIPT Systems
Muhammad Zeeshan Mumtaz, Mohammadali Mohammadi, Hien Quoc Ngo +2
The paper proposes a power‑efficient design for extra‑large MIMO systems that serve simultaneous wireless information and power transfer (SWIPT) users in both near‑field and far‑fi…
Modular-CAPA-Based Communication Systems: Joint Activation and Beamforming Design
Mengyu Qian, Xidong Mu, Li You +1
The paper studies a modular continuous aperture array (CAPA) system where only selected sub‑apertures are activated, and proposes joint activation and beamforming designs to maximi…
Spatial Limits of Fluid Antenna Systems
Amy S. Inwood, Peter J. Smith, Rajitha Senanayake +1
Continuous fluid antenna systems (CFASs) represent an upper bound on the spatial diversity performance of fluid antenna systems (FASs), achieved when antennas may be positioned any…
Max-Min Rate Fairness Optimization for Multi-User Pinching-Antenna NOMA Systems
Mahmoud AlaaEldin, Amy Inwood, Xidong Mu +1
Pinching-antenna systems (PASs) can overcome signal blockage by repositioning dielectric radiating elements, called pinching antennas (PAs), along meter-scale waveguides to create…
Sparse Channel Estimation for SIM-based mmWave Near-Field Communications
Jiancheng An, Enyu Shi, Jiayi Zhang +4
In this paper, we address the channel estimation (CE) problem in SIM-based multi-user (MU) millimeter-wave (mmWave) near-field communication systems. To address the severe path los…
