Joint Channel Estimation and Data Detection for Multi-LEO-Satellite Cell-Free OTFS Uplinks
Gangle Sun, Tianhao Liu, Jun Tian +6
Cell-free networks formed by multiple low Earth orbit (LEO) satellites offer a promising architecture for ubiquitous connectivity, but their cooperative reception is challenged by…
Toward Alias-Free Channel Extrapolation in Upper Mid-Band Systems: A Spatial-Frequency-Temporal Tensor Learning Approach
Jiawei Zhuang, Hongwei Hou, Yafei Wang +4
Upper mid-band massive multiple-input multiple-output (MIMO) offers a favorable capacity-coverage trade-off for next-generation wireless systems, but its large antenna arrays, wide…
A Channel Knowledge Map-Driven Two-Stage Coordinated User Scheduling in Multi-Cell Massive MIMO Systems
Jiayang Wan, Hongwei Hou, Jiawei Zhuang +2
This paper investigates narrowband coordinated user scheduling in multi-cell massive multiple-input multiple-output (MIMO) systems. We formulate the problem under a spectral-effici…
Semantic Satellite Communications for Synchronized Audiovisual Reconstruction
Fangyu Liu, Peiwen Jiang, Wenjin Wang +2
Satellite communications face severe bottlenecks in supporting high-fidelity synchronized audiovisual services, as conventional schemes struggle with cross-modal coherence under fl…
