Mitigating Mixed-field Interference in Near-field and Far-field Communications: An Antenna Selection Approach
Tianyu Liu, Changsheng You, Chao Zhou +3
In mixed near-field and far-field systems, the nonorthogonality between near-field and far-field channels may cause severe inter-user interference and hence degrade rate performanc…
Physical-Layer Security in Mixed Near-Field and Far-Field Communication Systems
Tianyu Liu, Changsheng You, Cong Zhou +4
Extremely large-scale arrays (XL-arrays) have emerged as a promising technology to improve the spectrum efficiency and spatial resolution of future wireless systems. Different from…
Deployment Optimization for XL-IRS Assisted Multi-User Communications
Chao Zhou, Changsheng You, Tianyu Liu +1
In this paper, we study the deployment optimization for an extremely large-scale intelligent reflecting surface (XL-IRS) assisted multi-user communication system, within which the…
Semantic-Relay-Aided Text Transmission: Placement Optimization and Bandwidth Allocation
Tianyu Liu, Changsheng You, Zeyang Hu +3
Semantic communication has emerged as a promising technology to break the Shannon limit by extracting the meaning of source data and sending relevant semantic information only. How…
Multiuser Resource Allocation for Semantic-Relay-Aided Text Transmissions
Zeyang Hu, Tianyu Liu, Changsheng You +2
Semantic communication (SemCom) is an emerging technology that extracts useful meaning from data and sends only relevant semantic information. Thus, it has the great potential to i…
