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…
Robust Transceiver Design for Covert Integrated Sensing and Communications With Imperfect CSI
Yuchen Zhang, Wanli Ni, Jianquan Wang +4
We propose a robust transceiver design for a covert integrated sensing and communications (ISAC) system with imperfect channel state information (CSI). Considering both bounded and…
Near-Field Channel Estimation in Mixed LoS/NLoS Environments for Extremely Large-Scale MIMO Systems
Yu Lu, Linglong Dai
Accurate channel model and channel estimation are essential to empower extremely large-scale MIMO (XL-MIMO) in 6G networks with ultra-high spectral efficiency. With the sharp incre…
Age Optimal Sampling Under Unknown Delay Statistics
Haoyue Tang, Yuchao Chen, Jintao Wang +2
This paper revisits the problem of sampling and transmitting status updates through a channel with random delay under a sampling frequency constraint \cite{sun_17_tit}. We use the…
Pattern-Division Multiplexing for Multi-User Continuous-Aperture MIMO
Zijian Zhang, Linglong Dai
In recent years, thanks to the advances in meta-materials, the concept of continuous-aperture MIMO (CAP-MIMO) is reinvestigated to achieve improved communication performance with l…
Capacity Enhancement for Reconfigurable Intelligent Surface-Aided Wireless Network: from Regular Array to Irregular Array
Ruochen Su, Linglong Dai, Jingbo Tan +2
Reconfigurable intelligent surface (RIS) is promising for future 6G wireless communications. However, the increased number of RIS elements results in the high overhead for channel…
