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…
NOMA-Based Hybrid Satellite-UAV-Terrestrial Networks for Beyond 5G Maritime Internet of Things
Xinran Fang, Wei Feng, Yanmin Wang +3
Current fifth-generation (5G) networks do not cover maritime areas, causing difficulties in developing maritime Internet of Things (IoT). To tackle this problem, we establish a nea…
5G Embraces Satellites for 6G Ubiquitous IoT: Basic Models for Integrated Satellite Terrestrial Networks
Xinran Fang, Wei Feng, Te Wei +3
Terrestrial communication networks mainly focus on users in urban areas but have poor coverage performance in harsh environments, such as mountains, deserts, and oceans. Satellites…
Impact and Calibration of Nonlinear Reciprocity Mismatch in Massive MIMO
Rongjiang Nie, Li Chen, Nan Zhao +3
Time-division-duplexing massive multiple-input multiple-output (MIMO) systems estimate the channel state information (CSI) by leveraging the uplink-downlink channel reciprocity, wh…
UAV Swarm-Enabled Aerial CoMP: A Physical Layer Security Perspective
Xuanxuan Wang, Wei Feng, Yunfei Chen +1
Unlike aerial base station enabled by a single unmanned aerial vehicle (UAV), aerial coordinated multiple points (CoMP) can be enabled by a UAV swarm. In this case, the management…
Maritime Coverage Enhancement Using UAVs Coordinated with Hybrid Satellite-Terrestrial Networks
Xiangling Li, Wei Feng, Yunfei Chen +2
Due to its agile maneuverability, unmanned aerial vehicles (UAVs) have shown great promise for ondemand communications. In practice, UAV-aided aerial base stations are not separate…
Unilateral Left-Tail Anderson Darling Test Based Spectrum Sensing with Laplacian Noise
