Intelligent Reflecting Surface with Discrete Phase Shifts: Channel Estimation and Passive Beamforming
Changsheng You, Beixiong Zheng, Rui Zhang
In this paper, we consider an intelligent reflecting surface (IRS)-aided single-user system where an IRS with discrete phase shifts is deployed to assist the uplink communication.…
Channel Estimation and Passive Beamforming for Intelligent Reflecting Surface: Discrete Phase Shift and Progressive Refinement
Changsheng You, Beixiong Zheng, Rui Zhang
Prior studies on Intelligent Reflecting Surface (IRS) have mostly assumed perfect channel state information (CSI) available for designing the IRS passive beamforming as well as the…
Hybrid Offline-Online Design for UAV-Enabled Data Harvesting in Probabilistic LoS Channel
Changsheng You, Rui Zhang
This paper considers an unmanned aerial vehicle (UAV)-enabled wireless sensor network (WSN) in urban areas, where a UAV is deployed to collect data from distributed sensor nodes (S…
3D Trajectory Optimization in Rician Fading for UAV-Enabled Data Harvesting
Changsheng You, Rui Zhang
In this paper, we consider a UAV-enabled WSN where a flying UAV is employed to collect data from multiple sensor nodes (SNs). Our objective is to maximize the minimum average data…
