Wideband Near-Field Sensing in ISAC: Unified Algorithm Design and Decoupled Effect Analysis
Ruiyun Zhang, Zhaolin Wang, Zhiqing Wei +3
To advance integrated sensing and communications (ISAC) in sixth-generation (6G) extremely large-scale multiple-input multiple-output (XL-MIMO) networks, a low-complexity compresse…
Symbol Timing Synchronization and Signal Detection for Ambient Backscatter Communication
Yuxin Li, Guangyue Lu, Yinghui Ye +2
Ambient backscatter communication (AmBC) enables ambient Internet of Things (AIoT) devices to achieve ultra-low-power, low-cost, and massive connectivity. Most existing AmBC studie…
Resilience of Mega-Satellite Constellations: How Node Failures Impact Inter-Satellite Networking Over Time?
Binquan Guo, Zehui Xiong, Zhou Zhang +4
Mega-satellite constellations have the potential to leverage inter-satellite links to deliver low-latency end-to-end communication services globally, thereby extending connectivity…
Subspace Fitting Approach for Wideband Near-Field Localization
Ruiyun Zhang, Zhaolin Wang, Zhiqing Wei +3
Two subspace fitting approaches are proposed for wideband near-field localization. Unlike in conventional far-field systems, where distance and angle can be estimated separately, s…
Joint Traffic Reshaping and Channel Reconfiguration in RIS-assisted Semantic NOMA Communications
Songhan Zhao, Yusi Long, Lanhua Li +3
In this paper, we consider a semantic-aware reconfigurable intelligent surface (RIS)-assisted wireless network, where multiple semantic users (SUs) simultaneously transmit semantic…
Decentralized Semantic Federated Learning for Real-Time Public Safety Tasks: Challenges, Methods, and Directions
Baosheng Li, Weifeng Gao, Zehui Xiong +3
Public safety tasks rely on the collaborative functioning of multiple edge devices (MEDs) and base stations (BSs) in different regions, consuming significant communication energy a…
