On Secure Uplink Transmission in Hybrid RF-FSO Cooperative Satellite-Aerial-Terrestrial Networks
Yuanyuan Ma, Tiejun Lv, Gaofeng Pan +2
This work investigates the secrecy outage performance of the uplink transmission of a radio-frequency (RF)-free-space optical (FSO) hybrid cooperative satellite-aerial-terrestrial…
Joint Mobility Control and MEC Offloading for Hybrid Satellite-Terrestrial-Network-Enabled Robots
Peng Wei, Wei Feng, Yanmin Wang +3
Benefiting from the fusion of communication and intelligent technologies, network-enabled robots have become important to support future machine-assisted and unmanned applications.…
Coexistence Designs of Radar and Communication Systems in a Multi-path Scenario
Haoyu Zhang, Li Chen, Kaifeng Han +2
The focus of this study is on the spectrum sharing between multiple-input multiple-output (MIMO) communications and co-located MIMO radar systems in multi-path environments. The ma…
Integrating Satellites and Mobile Edge Computing for 6G Wide-Area Edge Intelligence: Minimal Structures and Systematic Thinking
Yueshan Lin, Wei Feng, Ting Zhou +4
The sixth-generation (6G) network will shift its focus to supporting everything including various machine-type devices (MTDs) in an everyone-centric manner. To ubiquitously cover t…
Cramér-Rao Bounds of Near-Field Positioning Based on Electromagnetic Propagation Model
