Superimposed RIS-phase Modulation for MIMO Communications: A Novel Paradigm of Information Transfer
Jiacheng Yao, Jindan Xu, Wei Xu +2
Reconfigurable intelligent surface (RIS) is regarded as an important enabling technology for the sixth-generation (6G) network. Recently, modulating information in reflection patte…
Imperfect CSI: A Key Factor of Uncertainty to Over-the-Air Federated Learning
Jiacheng Yao, Zhaohui Yang, Wei Xu +2
Over-the-air computation (AirComp) has recently been identified as a prominent technique to enhance communication efficiency of wireless federated learning (FL). This letter invest…
GoMORE: Global Model Reuse for Resource-Constrained Wireless Federated Learning
Jiacheng Yao, Zhaohui Yang, Wei Xu +2
Due to the dynamics of wireless environment and limited bandwidth, wireless federated learning (FL) is challenged by frequent transmission errors and incomplete aggregation from de…
Robust Beamforming Design for RIS-aided Cell-free Systems with CSI Uncertainties and Capacity-limited Backhaul
Jiacheng Yao, Jindan Xu, Wei Xu +3
In this paper, we consider the robust beamforming design in a reconfigurable intelligent surface (RIS)-aided cell-free (CF) system considering the channel state information (CSI) u…
