STAR-RIS-Assisted-Full-Duplex Jamming Design for Secure Wireless Communications System
Yun Wen, Gaojie Chen, Sisai Fang +3
Physical layer security (PLS) technologies are expected to play an important role in the next-generation wireless networks, by providing secure communication to protect critical an…
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…
Sensing User's Activity, Channel, and Location with Near-Field Extra-Large-Scale MIMO
Li Qiao, Anwen Liao, Zhuoran Li +7
This paper proposes a grant-free massive access scheme based on the millimeter wave (mmWave) extra-large-scale multiple-input multiple-output (XL-MIMO) to support massive Internet-…
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…
MDD-Enabled Two-Tier Terahertz Fronthaul in Indoor Industrial Cell-Free Massive MIMO
Bohan Li, Diego Dupleich, Guoqing Xia +4
To make indoor industrial cell-free massive multiple-input multiple-output (CF-mMIMO) networks free from wired fronthaul, this paper studies a multicarrier-division duplex (MDD)-en…
A Design of Low-Projection SCMA Codebooks for Ultra-Low Decoding Complexity in Downlink IoT Networks
Qu Luo, Zilong Liu, Gaojie Chen +3
This paper conceives a novel sparse code multiple access (SCMA) codebook design which is motivated by the strong need for providing ultra-low decoding complexity and good error per…
A Novel Multi-Task Learning Empowered Codebook Design for Downlink SCMA Networks
Qu Luo, Zilong Liu, Gaojie Chen +2
Sparse code multiple access (SCMA) is a promising code-domain non-orthogonal multiple access (NOMA) scheme for the enabling of massive machine-type communication. In SCMA, the desi…
