Beam Training for RIS-Aided ISAC Systems
Jinho Yang, Hyeongtaek Lee, Junil Choi
As a key technology for 6G, integrated sensing and communication (ISAC) is receiving considerable attention, and deploying a reconfigurable intelligent surface (RIS) can enhance bo…
Efficient Solvers for Coupling-Aware Beamforming in Continuous Aperture Arrays
Geonhee Lee, Kwonyeol Park, Hyeongjun Park +2
In continuous aperture arrays (CAPAs), careful consideration of the underlying physics is essential, among which electromagnetic (EM) mutual coupling plays a critical role in beamf…
Evolution of UE in Massive MIMO Systems for 6G: From Passive to Active
Kwonyeol Park, Hyuckjin Choi, Geonho Han +4
As wireless networks continue to evolve, stringent latency and reliability requirements and highly dynamic channels expose fundamental limitations of gNB-centric massive multiple-i…
Anomaly Detection-Based UE-Centric Inter-Cell Interference Suppression
Kwonyeol Park, Hyuckjin Choi, Beomsoo Ko +7
The increasing spectral reuse can cause significant performance degradation due to interference from neighboring cells. In such scenarios, developing effective interference suppres…
Downlink Channel Estimation for mmWave Systems with Impulsive Interference
Kwonyeol Park, Gyoseung Lee, Hyeongtaek Lee +2
In this paper, we investigate a channel estimation problem in a downlink millimeter-wave (mmWave) multiple-input multiple-output (MIMO) system, which suffers from impulsive interfe…
Robust Transmission Design for Active RIS-Aided Systems
Jinho Yang, Hyeongtaek Lee, Junil Choi
Different from conventional passive reconfigurable intelligent surfaces (RISs), incident signals and thermal noise can be amplified at active RISs. By exploiting the amplifying cap…
