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…
Cell-Free Integrated Sensing and Communication: Principles, Advances, and Future Directions
Diluka Galappaththige, Mohammadali Mohammadi, Gayan Aruma Baduge +1
Cell-free (CF) integrated sensing and communication (ISAC) combines CF architecture with ISAC. CF employs distributed access points, eliminates cell boundaries, and enhances covera…
Availability of Aerial Heterogeneous Networks for Reliable Emergency Communications
Teng Wu, Jiandong Li, Junyu Liu +4
We investigate network availability (NA) in aerial heterogeneous networks (AHetNets) for effective emergency rescue, where diverse delay-constrained communication services must be…
Near-Field Energy Harvesting Using XL-MIMO Over Non-Stationary Channels
Muhammad Zeeshan Mumtaz, Mohammadali Mohammadi, Hien Quoc Ngo +1
This paper explores the maximization of the harvested power efficiency (HPE) in a modular extremely large multiple-input multiple-output (XL-MIMO) system, which supports energy har…
Near-Field SWIPT Using XL-MIMO: Power Allocation and Subarray Activation
Muhammad Zeeshan Mumtaz, Mohammadali Mohammadi, Hien Quoc Ngo +1
This paper investigates the simultaneous wireless information and power transfer (SWIPT) capability of a modular extremely large multiple-input multiple-output (XL-MIMO) system, in…
