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…
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…
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…
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…
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…
Static IRS Meets Distributed MIMO: A New Architecture for Dynamic Beamforming
Guangji Chen, Qingqing Wu, Celimuge Wu +3
Intelligent reflecting surface (IRS) has been considered as a revolutionary technology to enhance the wireless communication performance. To cater for multiple mobile users, adjust…
