Multi-Group Multicasting Systems Using Multiple RISs
Hyeongtaek Lee, Seungsik Moon, Youngjoo Lee +3
In this paper, practical utilization of multiple distributed reconfigurable intelligent surfaces (RISs), which are able to conduct group-specific operations, for multi-group multic…
WiThRay: A Versatile Ray-Tracing Simulator for Smart Wireless Environments
Hyuckjin Choi, Jaehoon Chung, Jaeky Oh +2
This paper presents the development and evaluation of WiThRay, a new wireless three-dimensional ray-tracing (RT) simulator. RT-based simulators are widely used for generating reali…
Channel Estimation for Reconfigurable Intelligent Surface with a few Active Elements
Gyoseung Lee, Hyeongtaek Lee, Jaeky Oh +2
In this paper, a channel estimation technique for reconfigurable intelligent surface (RIS)-aided multi-user multiple-input single-output communication systems is proposed. By deplo…
Bayesian Channel Estimation for Intelligent Reflecting Surface-Aided mmWave Massive MIMO Systems With Semi-Passive Elements
In-soo Kim, Mehdi Bennis, Jaeky Oh +2
In this paper, we propose a Bayesian channel estimator for intelligent reflecting surface-aided (IRS-aided) millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) s…
