Practical Channel Estimation and Phase Shift Design for Intelligent Reflecting Surface Empowered MIMO Systems
Sucheol Kim, Hyeongtaek Lee, Jihoon Cha +3
In this paper, channel estimation techniques and phase shift design for intelligent reflecting surface (IRS)-empowered single-user multiple-input multiple-output (SU-MIMO) systems…
Complete Power Reallocation for MU-MIMO under Per-Antenna Power Constraint
Sucheol Kim, Hyeongtaek Lee, Hwanjin Kim +2
This paper proposes a beamforming method under a per-antenna power constraint (PAPC). Although many beamformer designs with the PAPC need to solve complex optimization problems, th…
Downlink Channel Reconstruction for Spatial Multiplexing in Massive MIMO Systems
Hyeongtaek Lee, Hyuckjin Choi, Hwanjin Kim +4
To get channel state information (CSI) at a base station (BS), most of researches on massive multiple-input multiple-output (MIMO) systems consider time division duplexing (TDD) to…
Multi-Vehicle Velocity Estimation Using IEEE 802.11ad Waveform
Geonho Han, Sucheol Kim, Junil Choi
Wireless communication systems are to use millimeter-wave (mmWave) spectra, which can enable extra radar functionalities. In this paper, we propose a multi-target velocity estimati…
