ISAC with Co-Prime Arrays: Virtual-Aperture Sensing and uplink downlink communications
Jing Zhang, Yuxiao Liu, Jiayi Sun +2
Integrated sensing and communication (ISAC) enables simultaneous communication and environmental sensing in unmanned aerial vehicle (UAV) networks, but its performance is constrain…
Towards Standardizing OTFS: A Candidate Waveform for Next-Generation Wireless Networks
Mingcheng Nie, Ruoxi Chong, Shuangyang Li +5
The standardization of the sixth-generation (6G) has recently commenced to address the rapidly growing demands for enhanced wireless network services. Nevertheless, existing wirele…
Information-Theoretic Secure Aggregation in Decentralized Networks
Xiang Zhang, Zhou Li, Shuangyang Li +3
Motivated by the increasing demand for data security in decentralized federated learning (FL) and stochastic optimization, we formulate and investigate the problem of information-t…
Information-Theoretic Decentralized Secure Aggregation with Passive Collusion Resilience
Xiang Zhang, Zhou Li, Shuangyang Li +3
In decentralized federated learning (FL), multiple clients collaboratively learn a shared machine learning (ML) model by leveraging their privately held datasets distributed across…
Resource Allocation for Multi-waveguide Pinching Antenna-assisted Broadcast Networks
Ruotong Zhao, Shaokang Hu, Deepak Mishra +1
In this paper, we investigate the resource allocation for multi-dielectric waveguide-assisted broadcast systems, where each waveguide employs multiple pinching antennas (PAs), aimi…
