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…
Intelligent Surface Empowered Integrated Sensing and Communication: From Coexistence to Reciprocity
Kaitao Meng, Qingqing Wu, Christos Masouros +2
Integrated sensing and communication (ISAC) has attracted growing interests for sixth-generation (6G) and beyond wireless networks. The primary challenges faced by highly efficient…
Reconfigurable Intelligent Surface Aided Space Shift Keying With Imperfect CSI
Xusheng Zhu, Wen Chen, Qingqing Wu +4
In this paper, we investigate the performance of reconfigurable intelligent surface (RIS)-aided spatial shift keying (SSK) wireless communication systems with imperfect channel sta…
Performance Analysis of RIS-Aided Double Spatial Scattering Modulation for mmWave MIMO Systems
Xusheng Zhu, Wen Chen, Qingqing Wu +4
In this paper, we investigate a practical structure of reconfigurable intelligent surface (RIS)-based double spatial scattering modulation (DSSM) for millimeter-wave (mmWave) multi…
Intelligent Reflecting Surface Aided MIMO Networks: Distributed or Centralized Architecture?
Guangji Chen, Qingqing Wu, Wen Chen +4
We investigate the capacity of a broadcast channel with a multi-antenna base station (BS) sending independent messages to multiple users, aided by IRSs with N elements. In particul…
Intelligent Reflecting Surface Assisted Localization: Performance Analysis and Algorithm Design
Meng Hua, Qingqing Wu, Wen Chen +3
The target sensing/localization performance is fundamentally limited by the line-of-sight link and severe signal attenuation over long distances. This paper considers a challenging…
