Large Language Model Empowered CSI Feedback in Massive MIMO Systems
Jie Wu, Wei Xu, Le Liang +2
Despite the success of large language models (LLMs) across domains, their potential for efficient channel state information (CSI) compression and feedback in frequency division dup…
Joint MIMO Transceiver and Reflector Design for Reconfigurable Intelligent Surface-Assisted Communication
Yaqiong Zhao, Jindan Xu, Wei Xu +4
In this paper, we consider a reconfigurable intelligent surface (RIS)-assisted multiple-input multiple-output communication system with multiple antennas at both the base station (…
Digital versus Analog Transmissions for Federated Learning over Wireless Networks
Jiacheng Yao, Wei Xu, Zhaohui Yang +3
In this paper, we quantitatively compare these two effective communication schemes, i.e., digital and analog ones, for wireless federated learning (FL) over resource-constrained ne…
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…
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…
