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…
Channel Characterization of IRS-assisted Resonant Beam Communication Systems
Wen Fang, Wen Chen, Qingqing Wu +3
To meet the growing demand for data traffic, spectrum-rich optical wireless communication (OWC) has emerged as a key technological driver for the development of 6G. The resonant be…
Cramer-Rao Bound Minimization for Movable Antenna-Assisted Multiuser Integrated Sensing and Communications
Haoran Qin, Wen Chen, Qingqing Wu +3
This paper investigates a movable antenna (MA)-assisted multiuser integrated sensing and communication (ISAC) system, where the base station (BS) and communication users are all eq…
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 Enhanced NOMA Short-Packet Transmission
Xinyuan He, Wen Chen, Qingqing Wu +2
This letter investigates a short-packet downlink transmission system using non-orthogonal multiple access (NOMA) enhanced via movable antenna (MA). We focuses on maximizing the eff…
