System-Level Evaluation of LEO Satellite Communications Under Service-Driven Traffic Dynamics
Miyeon Lee, Dong-Hyun Jung, Sucheol Kim +2
As low Earth orbit (LEO) satellite communications take shape on a global scale, system-level evaluation has become essential for a rigorous understanding of their performance chara…
Analyzing Downlink Coverage in Clustered Low Earth Orbit Satellite Constellations: A Stochastic Geometry Approach
Miyeon Lee, Sucheol Kim, Minje Kim +2
Satellite networks are emerging as vital solutions for global connectivity beyond 5G. As companies such as SpaceX, OneWeb, and Amazon are poised to launch a large number of satelli…
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…
Efficient Channel AoD/AoA Estimation Using Widebeams for Millimeter Wave MIMO Systems
Hyeongtaek Lee, Sucheol Kim, Junil Choi
Using millimeter-wave (mmWave) bands is expected to provide high data rates through large licensed and unlicensed spectrum. Due to large path loss and sparse scattering propagation…
