Adaptive Beam Hopping and Power Control for Dual-Layer Over-the-Air Online Federated Learning in LEO Satellite Networks
Zhendong Li, Shaojie Wang, Zhou Su +5
This paper investigates over-the-air (OTA) computation enabled online federated learning (FL) in low-Earth orbit (LEO) satellite networks. Specifically, we consider a dual-layer OT…
Beamforming Design and Multi-User Scheduling in Transmissive RIS Enabled Distributed Cooperative ISAC Networks with RSMA
Ziwei Liu, Wen Chen, Qingqing Wu +4
In this paper, we propose a novel transmissive reconfigurable intelligent surface (TRIS) transceiver-empowered distributed cooperative integrated sensing and communication (ISAC) n…
Multiple Intelligent Reflecting Surfaces Collaborative Wireless Localization System
Ziheng Zhang, Wen Chen, Qingqing Wu +4
This paper studies a multiple intelligent reflecting surfaces (IRSs) collaborative localization system where multiple semi-passive IRSs are deployed in the network to locate one or…
Movable Antenna Empowered Downlink NOMA Systems: Power Allocation and Antenna Position Optimization
Yufeng Zhou, Wen Chen, Qingqing Wu +2
This paper investigates a novel communication paradigm employing movable antennas (MAs) within a multiple-input single-output (MISO) non-orthogonal multiple access (NOMA) downlink…
Elements Allocation for Joint Active and Passive IRS Aided Wireless Communications: A Rate-Maximization Perspective
Chaoying Huang, Wen Chen, Qingqing Wu +1
Unlike previous works that focused solely on passive intelligent reflecting surface (PIRS) or active IRS (AIRS), a novel joint AIRS and PIRS architecture has been developed to flex…
Antenna Positioning and Beamforming Design for Fluid-Antenna Enabled Multi-user Downlink Communications
Haoran Qin, Wen Chen, Zhendong Li +3
This paper investigates a multiple input single output (MISO) downlink communication system in which users are equipped with fluid antennas (FAs). First, we adopt a field-response…
