High-Efficiency Urban 3D Radio Map Estimation Based on Sparse Measurements
Xinwei Chen, Xiaofeng Zhong, Zijian Zhang +2
Recent widespread applications for unmanned aerial vehicles (UAVs) -- from infrastructure inspection to urban logistics -- have prompted an urgent need for high-accuracy three-dime…
Ice-Filling: Near-Optimal Channel Estimation for Dense Array Systems
Mingyao Cui, Zijian Zhang, Linglong Dai +1
By deploying a large number of antennas with sub-half-wavelength spacing in a compact space, dense array systems (DASs) can fully unleash the multiplexing and diversity gains of li…
Successive Bayesian Reconstructor for FAS Channel Estimation
Zijian Zhang, Jieao Zhu, Linglong Dai +1
Fluid antenna systems (FASs) can reconfigure their locations freely within a spatially continuous space. To keep favorable antenna positions, the channel state information (CSI) ac…
Successive Bayesian Reconstructor for Channel Estimation in Fluid Antenna Systems
Zijian Zhang, Jieao Zhu, Linglong Dai +1
Fluid antenna systems (FASs) can reconfigure their antenna locations freely within a spatially continuous space. To keep favorable antenna positions, the channel state information…
Reconfigurable Intelligent Surfaces for 6G: Nine Fundamental Issues and One Critical Problem
Zijian Zhang, Linglong Dai
Thanks to the recent advances in metamaterials, reconfigurable intelligent surface (RIS) has emerged as a promising technology for future 6G wireless communications. Benefiting fro…
Active RISs: Signal Modeling, Asymptotic Analysis, and Beamforming Design
Zijian Zhang, Linglong Dai, Xibi Chen +4
Reconfigurable intelligent surfaces (RISs) have emerged as a candidate technology for future 6G networks. However, due to the "multiplicative fading" effect, the existing passive R…
