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…
Beamforming Design for Multiuser Transmission Through Reconfigurable Intelligent Surface
Zhaohui Yang, Wei Xu, Chongwen Huang +2
This paper investigates the problem of resource allocation for multiuser communication networks with a reconfigurable intelligent surface (RIS)-assisted wireless transmitter. In th…
Multi-Agent Deep Reinforcement Learning Based Trajectory Planning for Multi-UAV Assisted Mobile Edge Computing
Liang Wang, Kezhi Wang, Cunhua Pan +3
An unmanned aerial vehicle (UAV)-aided mobile edge computing (MEC) framework is proposed, where several UAVs having different trajectories fly over the target area and support the…
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…
Chimbuko: A Workflow-Level Scalable Performance Trace Analysis Tool
Sungsoo Ha, Wonyong Jeong, Gyorgy Matyasfalvi +11
