Joint Localization and Orientation with Triple-Beam Fingerprints in Massive MIMO-OFDM
Yu Zhao, Zhenzhou Jin, Jinke Tang +4
With the widespread application of location-based services, fingerprint-based localization has demonstrated advantages in environments with complex signal propagation. Deep learnin…
Jointly Correlated Dual-Side Fluid Antenna System
Zhentian Zhang, Yuanhui Wu, Kai-Kit Wong +2
Fluid antenna systems (FASs) have introduced a new paradigm for wireless system design by revealing how mutual correlation can be exploited to harvest inherent spatial diversity. W…
CSI-tuples-based 3D Channel Fingerprints Construction Assisted by MultiModal Learning
Chenjie Xie, Li You, Ruirong Chen +2
Low-altitude communications can promote the integration of aerial and terrestrial wireless resources, expand network coverage, and enhance transmission quality, thereby empowering…
Sphere Decoding Revisited
Zheng Wang, Cong Ling, Shi Jin +2
In this paper, the paradigm of sphere decoding (SD) for solving the integer least square problem (ILS) is revisited, where extra degrees of freedom are introduced to exploit the de…
Joint Low-Rank and Sparse Bayesian Channel Estimation for Ultra-Massive MIMO Communications
Jianghan Ji, Cheng-Xiang Wang, Shuaifei Chen +3
This letter investigates channel estimation for ultra-massive multiple-input multiple-output (MIMO) communications. We propose a joint low-rank and sparse Bayesian estimation (LRSB…
Finite-blocklength Fluid Antenna Systems With Spatial Block-Correlation Channel Model
Zhentian Zhang, Kai-Kit Wong, David Morales-Jimenez +4
Massive connectivity with ultra-low latency and high reliability necessitates fundamental advances in future communication networks operating under finite-blocklength (FBL) transmi…
