Wireless Image Transmission with Semantic and Security Awareness
Maojun Zhang, Yang Li, Zezhong Zhang +2
Semantic communication is an increasingly popular framework for wireless image transmission due to its high communication efficiency. With the aid of the joint-source-and-channel (…
Spatially Sparse Precoding in Wideband Hybrid Terahertz Massive MIMO Systems
Jiabao Gao, Caijun Zhong, Geoffrey Ye Li +2
In terahertz (THz) massive multiple-input multiple-output (MIMO) systems, the combination of huge bandwidth and massive antennas results in severe beam split, thus making the conve…
Over-the-Air Split Machine Learning in Wireless MIMO Networks
Yuzhi Yang, Zhaoyang Zhang, Yuqing Tian +4
In split machine learning (ML), different partitions of a neural network (NN) are executed by different computing nodes, requiring a large amount of communication cost. To ease com…
Multiple RISs Assisted Cell-Free Networks With Two-timescale CSI: Performance Analysis and System Design
Xu Gan, Caijun Zhong, Chongwen Huang +2
Reconfigurable intelligent surface (RIS) can be employed in a cell-free system to create favorable propagation conditions from base stations (BSs) to users via configurable element…
IRS-Based Integrated Location Sensing and Communication for mmWave SIMO Systems
Xiaoling Hu, Chenxi Liu, Mugen Peng +1
In this paper, we establish an integrated sensing and communication (ISAC) system based on a distributed semi-passive intelligent reflecting surface (IRS), which allows location se…
Location Sensing and Beamforming Design for IRS-Enabled Multi-User ISAC Systems
Zhouyuan Yu, Xiaoling Hu, Chenxi Liu +2
This paper explores the potential of the intelligent reflecting surface (IRS) in realizing multi-user concurrent communication and localization, using the same time-frequency resou…
