Enhancing Signal Space Diversity for SCMA Over Rayleigh Fading Channels
Qu Luo, Zilong Liu, Gaojie Chen +1
Sparse code multiple access (SCMA) is a promising technique for the enabling of massive connectivity in future machine-type communication networks, but it suffers from a limited di…
Enhancement of Direct LEO Satellite-to-Smartphone Communications by Distributed Beamforming
Zhuoao Xu, Gaojie Chen, Ryan Fernandez +2
The low earth orbit (LEO) satellite network is undergoing rapid development with the maturing of satellite communications and rocket launch technologies, and the demand for a globa…
Enhancement of Satellite-to-Phone Link Budget by Using Distributed Beamforming
Zhuoao Xu, Yue Gao, Gaojie Chen +3
Small satellites in Low Earth Orbit (LEO) attract much attention from both industry and academia. The latest production and launch technologies constantly drive the development of…
Transformer-based Joint Source Channel Coding for Textual Semantic Communication
Shicong Liu, Zhen Gao, Gaojie Chen +2
The Space-Air-Ground-Sea integrated network calls for more robust and secure transmission techniques against jamming. In this paper, we propose a textual semantic transmission fram…
DoF Upper Bound on Three-User MISO Broadcast Channel with Two Antennas and Mixed CSIT
Shuo Zheng, Tong Zhang, Shuai Wang +4
With delayed and imperfect current channel state information at the transmitter (CSIT), namely mixed CSIT, the sum degrees-of-freedom (sum-DoF) in the two-user multiple-input multi…
Weighted Sum Rate Enhancement by Using Dual-Side IOS-Assisted Full-Duplex for Multi-User MIMO Systems
Sisai Fang, Gaojie Chen, Chong Huang +4
This paper established a novel multi-input multi-output (MIMO) communication network, in the presence of full-duplex (FD) transmitters and receivers with the assistance of dual-sid…
Rate-Splitting with Hybrid Messages: DoF Analysis of the Two-User MIMO Broadcast Channel with Imperfect CSIT
Tong Zhang, Yufan Zhuang, Gaojie Chen +4
Most of the existing research on degrees-of-freedom (DoF) with imperfect channel state information at the transmitter (CSIT) assume the messages are private, which may not reflect…
UAV-RIS-Aided Space-Air-Ground Integrated Network: Interference Alignment Design and DoF Analysis
Jingfu Li, Gaojie Chen, Tong Zhang +4
In space-air-ground integrated networks (SAGIN), receivers experience diverse interference from both the satellite and terrestrial transmitters. The heterogeneous structure of SAGI…
