Beamforming Optimization for IRS-Aided Communications with Transceiver Hardware Impairments
Hong Shen, Wei Xu, Shulei Gong +2
In this paper, we focus on intelligent reflecting surface (IRS) assisted multi-antenna communications with transceiver hardware impairments encountered in practice. In particular,…
Sliding Differential Evolution Scheduling for Federated Learning in Bandwidth-Limited Networks
Yifan Luo, Jindan Xu, Wei Xu +1
Federated learning (FL) in a bandwidth-limited network with energy-limited user equipments (UEs) is under-explored. In this paper, to jointly save energy consumed by the battery-li…
Cascaded Channel Estimation for IRS-assisted Mmwave Multi-antenna with Quantized Beamforming
Wenhui Zhang, Jindan Xu, Wei Xu +2
In this letter, we optimize the channel estimator of the cascaded channel in an intelligent reflecting surface (IRS)-assisted millimeter wave (mmWave) multi-antenna system. In this…
Distributed IRS with Statistical Passive Beamforming for MISO Communications
Yuwei Gao, Jindan Xu, Wei Xu +2
Intelligent reflecting surface (IRS) has recently been identified as a prominent technology with the ability of enhancing wireless communication by dynamically manipulating the pro…
Beamforming Design with Fast Convergence for IRS-Aided Full-Duplex Communication
Hong Shen, Tian Ding, Wei Xu +1
We study the beamforming optimization for an intelligent reflecting surface (IRS)-aided full-duplex (FD) communication system in this letter. Specifically, we maximize the sum rate…
Analog Versus Hybrid Precoding for Multiuser Massive MIMO with Quantized CSI Feedback
Yaqiong Zhao, Wei Xu, Jindan Xu +3
In this letter, we study the performance of a downlink multiuser massive multiple-input multiple-output (MIMO) system with sub-connected structure over limited feedback channels. T…
