Polar-Cap Codebook Design for MISO Rician Fading Channels with Limited Feedback
Sung Hyuck Hong, Sucheol Kim, Junil Choi +1
Most of the prior works on designing codebooks for limited feedback systems have not considered the presence of strong line-of-sight (LOS) channel component. This paper proposes th…
Massive MIMO Channel Prediction: Kalman Filtering vs. Machine Learning
Hwanjin Kim, Sucheol Kim, Hyeongtaek Lee +3
This paper focuses on channel prediction techniques for massive multiple-input multiple-output (MIMO) systems. Previous channel predictors are based on theoretical channel models,…
Beam Designs for Millimeter-Wave Backhaul with Dual-Polarized Uniform Planar Arrays
Sucheol Kim, Junil Choi, Jiho Song
This paper proposes hybrid beamforming designs for millimeter-wave (mmWave) multiple-input multiple-output (MIMO) backhaul systems equipped with uniform planar arrays (UPAs) of dua…
Beam Design for Millimeter-Wave Backhaul with Dual-Polarized Uniform Planar Arrays
Sucheol Kim, Junil Choi, Jiho Song
This paper proposes a beamforming design for millimeter-wave (mmWave) backhaul systems with dual-polarization antennas in uniform planar arrays (UPAs). The proposed design method o…
