Over-the-Air Aggregation for Federated Learning: Waveform Superposition and Prototype Validation
Huayan Guo, Yifan Zhu, Haoyu Ma +5
In this paper, we develop an orthogonal-frequency-division-multiplexing (OFDM)-based over-the-air (OTA) aggregation solution for wireless federated learning (FL). In particular, th…
Cascaded Channel Estimation for Intelligent Reflecting Surface Assisted Multiuser MISO Systems
Huayan Guo, Vincent K. N. Lau
This paper investigates the uplink cascaded channel estimation for intelligent-reflecting-surface (IRS)-assisted multi-user multiple-input-single-output systems. We focus on a sub-…
Weighted Sum-Rate Maximization for Reconfigurable Intelligent Surface Aided Wireless Networks

Reconfigurable intelligent surfaces (RIS) is a promising solution to build a programmable wireless environment via steering the incident signal in fully customizable ways with reco…
Model-Free Optimization for Reconfigurable Intelligent Surface with Statistical CSI
Huayan Guo, Ying-Chang Liang, Sa Xiao
In this paper, a single user multiple input single output downlink wireless communication system is investigated, in which multiple reconfigurable intelligent surfaces (RISs) are d…
Intelligent Reflecting Surface: A Programmable Wireless Environment for Physical Layer Security
Jie Chen, Ying-Chang Liang, Yiyang Pei +1
In this paper, we introduce an intelligent reflecting surface (IRS) to provide a programmable wireless environment for physical layer security. By adjusting the reflecting coeffici…
Large Intelligent Surface/Antennas (LISA): Making Reflective Radios Smart
Ying-Chang Liang, Ruizhe Long, Qianqian Zhang +3
Large intelligent surface/antennas (LISA), a two-dimensional artificial structure with a large number of reflective-surface/antenna elements, is a promising reflective radio techno…
