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…
Joint Transceiver Orientation Optimization for Rotatable-Antenna MIMO Capacity Maximization
Zheng Ailing, Wu Qingqing, Peng Xingxiang +3
Conventional multiple-input multiple-output (MIMO) systems mainly rely on fixed antenna arrays, which limits their capability to adapt the effective channel matrix to the propagati…
Engineering Favorable Propagation: Near-Field IRS Deployment for Spatial Multiplexing
Qingqing Wu, Yuxuan Chen, Guangji Chen +2
In intelligent reflecting surface IRS assisted multiple input multiple output MIMO systems, a strong line of sight LoS link is required to compensate for the severe cascaded path l…
Multi-IRS Aided ISAC System: Multi-Path Exploitation Versus Reduction
Guangji Chen, Qingqing Wu, Shihang Lu +2
This paper investigates a multi-intelligent reflecting surface (IRS) aided integrated sensing and communication (ISAC) system, where multiple IRSs are strategically deployed not on…
Spatial Multiplexing Oriented Channel Reconfiguration in Multi-IRS Aided MIMO Systems
Yuxuan Chen, Qingqing Wu, Guangji Chen +1
Spatial multiplexing plays a significant role in improving the capacity of multiple-input multiple-output (MIMO) communication systems. To improve the spectral efficiency (SE) of a…
Suppressing Beam Squint Effect For Near-Field Wideband Communication Through Movable Antennas
Yanze Zhu, Qingqing Wu, Yang Liu +2
In this correspondence, we study deploying movable antenna (MA) array in a wideband multiple-input-single-output (MISO) communication system, where near-field (NF) channel model is…
