Accelerating Federated Learning via Momentum Gradient Descent
Wei Liu, Li Chen, Yunfei Chen +1
Federated learning (FL) provides a communication-efficient approach to solve machine learning problems concerning distributed data, without sending raw data to a central server. Ho…
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…
Optimal Beamforming for Hybrid Satellite Terrestrial Networks with Nonlinear PA and Imperfect CSIT
Chengxiao Liu, Wei Feng, Yunfei Chen +2
In hybrid satellite-terrestrial networks (HSTNs), spectrum sharing is crucial to alleviate the "spectrum scarcity" problem. Therein, the transmit beams should be carefully designed…
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…
Hybrid Satellite-Terrestrial Communication Networks for the Maritime Internet of Things: Key Technologies, Opportunities, and Challenges
Te Wei, Wei Feng, Yunfei Chen +3
With the rapid development of marine activities, there has been an increasing number of maritime mobile terminals, as well as a growing demand for high-speed and ultra-reliable mar…
Unilateral Left-Tail Anderson Darling Test Based Spectrum Sensing with Laplacian Noise
Lijuan Jiang, Yongzhao Li, Yinghui Ye +3
This paper focuses on spectrum sensing under Laplacian noise. To remit the negative effects caused by heavy-tailed behavior of Laplacian noise, the fractional lower order moments (…
