Neural Kalman Filtering for Unknown Dynamics: Task-Aware Learning with a Koopman Backbone
Mintaek Oh, Jeonghun Park, Nir Shlezinger +2
Recent years have witnessed a growing interest in AI-aided Kalman filters. While emerging methodologies, such as KalmanNet, were shown to facilitate tracking in partially known sta…
Hybrid Precoding Revisited: Low-Dimensional Subspace Perspective for MU-MIMO Systems
Mintaek Oh, Jinseok Choi
This letter presents a low-complexity hybrid precoding framework for multiuser multiple-input multiple-output (MIMO) systems by leveraging a low-dimensional subspace property. Unde…
Space-Time Beamforming for LEO Satellite Communications
Jungbin Yim, Jinseok Choi, Jeonghun Park +2
Inter-beam interference poses a significant challenge in low Earth orbit (LEO) satellite communications due to dense satellite constellations. To address this issue, we introduce s…
Scalable Beamforming Design for Multi-RIS-Aided MU-MIMO Systems with Imperfect CSIT
Mintaek Oh, Jinseok Choi
This paper presents a scalable beamforming design for maximizing the spectral efficiency (SE) of multi-reconfigurable intelligent surface (RIS)-aided communications through joint o…
Spectrum Sharing Between Low Earth Orbit Satellite and Terrestrial Networks: A Stochastic Geometry Perspective Analysis
Daeun Kim, Jeonghun Park, Jinseok Choi +1
Low Earth orbit (LEO) satellite networks with mega constellations have the potential to provide 5G and beyond services ubiquitously. However, these networks may introduce mutual in…
FDD Massive MIMO: How to Optimally Combine UL Pilot and Limited DL CSI Feedback?
Jungyeon Kim, Jinseok Choi, Jeonghun Park +2
In frequency-division duplexing (FDD) multiple-input multiple-output (MIMO) systems, obtaining accurate downlink channel state information (CSI) for precoding is vastly challenging…
Nonlinear Self-Interference Cancellation With Learnable Orthonormal Polynomials for Full-Duplex Wireless Systems
Hyowon Lee, Jungyeon Kim, Geon Choi +3
Nonlinear self-interference cancellation (SIC) is essential for full-duplex communication systems, which can offer twice the spectral efficiency of traditional half-duplex systems.…
