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…
Analysis of Beam Misalignment Effect in Inter-Satellite FSO Links
Minje Kim, Hongjae Nam, Beomsoo Ko +4
Free-space optical (FSO) communication has emerged as a promising technology for inter-satellite links (ISLs) due to its high data rate, low power consumption, and reduced interfer…
Task-Based Quantization for Channel Estimation in RIS Empowered MmWave Systems
Gyoseung Lee, In-soo Kim, Yonina C. Eldar +4
In this paper, we investigate channel estimation for reconfigurable intelligent surface (RIS) empowered millimeter-wave (mmWave) multi-user single-input multiple-output communicati…
Machine Learning-based Channel Prediction in Wideband Massive MIMO Systems with Small Overhead for Online Training
Beomsoo Ko, Hwanjin Kim, Minje Kim +1
Channel prediction compensates for outdated channel state information in multiple-input multiple-output (MIMO) systems. Machine learning (ML) techniques have recently been implemen…
