Atomic Norm Minimization-based Low-Overhead Channel Estimation for RIS-aided MIMO Systems
Hyeonjin Chung, Sunwoo Kim
Large beam training overhead has been considered as one of main issues in the channel estimation for reconfigurable intelligent surface (RIS)-aided systems. In this paper, we propo…

Experimental Demonstration of Location-aware Beam Alignment
Junyeol Hong, Hyeonjin Chung, Sunwoo Kim
The main focus of beam alignment is to find the optimal beam which yields the largest received signal strength (RSS) with faster speed.In this paper, we demonstrate an efficient be…

Adaptive Beamwidth Control for mmWave Beam Tracking
Hyeonjin Chung, Sunwoo Kim
Traditional beam tracking methods have severe performance loss under the high mobility and narrow beam scenario. To alleviate the tracking performance degradation, we propose an ad…
