Load Balancing in Multi-Shell LEO Satellite Networks with Successive Interference Cancellation
Seyong Kim, Jeonghun Park, Jeffrey G. Andrews
Multi-shell low Earth orbit (LEO) networks can increase service opportunities, but altitude-dependent propagation can concentrate traffic on lower shells and create strong inter-sh…
Space-Time Adaptive Beamforming for Satellite Communications: Harnessing Doppler as New Signaling Dimensions
Hyeongtak Yun, Seyong Kim, Jeonghun Park
Low Earth orbit (LEO) satellite downlinks are fundamentally limited by severe channel correlation: the line-of-sight (LoS)-dominant propagation and high orbital altitude confine us…
Asymptotic Scaling Law Analysis of Multicast Satellite Communications with Massive MIMO
Seyong Kim, Jeonghun Park
In this paper, we consider a geostationary orbit (GEO) satellite communication system that employs massive multiple-input multiple-output (MIMO) for multicast transmission. By mode…
Multibeam Satellite Communications with Massive MIMO: Asymptotic Performance Analysis and Design Insights
Seyong Kim, Jinseok Choi, Wonjae Shin +2
To achieve high performance without substantial overheads associated with channel state information (CSI) of ground users, we consider a fixed-beam precoding approach, where a sate…
Spherical Point Process with Random Heights: New Approach for Modeling and Analysis of Downlink Satellite Networks
Seyong Kim, Jinseok Choi, Namyoon Lee +2
The Low Earth Orbit (LEO) satellite industry is undergoing rapid expansion, with operators competitively launching satellites due to the first-come, first-served principle governin…
