Over-the-Air Federated Averaging with Limited Power and Privacy Budgets
Na Yan, Kezhi Wang, Cunhua Pan +3
To jointly overcome the communication bottleneck and privacy leakage of wireless federated learning (FL), this paper studies a differentially private over-the-air federated averagi…
Performance Analysis and Low-Complexity Design for XL-MIMO with Near-Field Spatial Non-Stationarities
Kangda Zhi, Cunhua Pan, Hong Ren +4
Extremely large-scale multiple-input multiple-output (XL-MIMO) is capable of supporting extremely high system capacities with large numbers of users. In this work, we build a frame…
Device Scheduling for Over-the-Air Federated Learning with Differential Privacy
Na Yan, Kezhi Wang, Cunhua Pan +1
In this paper, we propose a device scheduling scheme for differentially private over-the-air federated learning (DP-OTA-FL) systems, referred to as S-DPOTAFL, where the privacy of…
Toward Secure and Private Over-the-Air Federated Learning
Na Yan, Kezhi Wang, Kangda Zhi +3
In this paper, a novel secure and private over-the-air federated learning (SP-OTA-FL) framework is studied where noise is employed to protect data privacy and system security. Spec…
Active RIS Versus Passive RIS: Which Is Superior with the Same Power Budget?
Kangda Zhi, Cunhua Pan, Hong Ren +2
This letter theoretically compares the active reconfigurable intelligent surface (RIS)-aided system with the passive RIS-aided system. For fair comparison, we consider that these t…
Meta-learning for RIS-assisted NOMA Networks
Yixuan Zou, Yuanwei Liu, Kaifeng Han +2
A novel reconfigurable intelligent surfaces (RISs)-based transmission framework is proposed for downlink non-orthogonal multiple access (NOMA) networks. We propose a quality-of-ser…
Downlink Analysis for Reconfigurable Intelligent Surfaces Aided NOMA Networks
Chao Zhang, Wenqiang Yi, Yuanwei Liu +2
By activating blocked users and altering successive interference cancellation (SIC) sequences, reconfigurable intelligent surfaces (RISs) become promising for enhancing non-orthogo…
User Cooperation for IRS-aided Secure SWIPT MIMO Systems
Gui Zhou, Cunhua Pan, Hong Ren +3
In this paper, intelligent reflecting surface (IRS) is proposed to enhance the physical layer security in the Rician fading channel where the angular direction of the eavesdropper…
Robust Transmission Design for Intelligent Reflecting Surface Aided Secure Communication Systems with Imperfect Cascaded CSI
Sheng Hong, Cunhua Pan, Hong Ren +3
In this paper, we investigate the design of robust and secure transmission in intelligent reflecting surface (IRS) aided wireless communication systems. In particular, a multi-ante…
