Low-Earth Orbit Satellite Network Analysis: Coverage under Distance-Dependent Shadowing
Jinseok Choi, Jeonghun Park, Junse Lee +1
This paper offers a thorough analysis of the coverage performance of Low Earth Orbit (LEO) satellite networks using a strongest satellite association approach, with a particular em…
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…
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…
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…
Block Orthogonal Sparse Superposition Codes for Communications: Low Error Rate, Low Latency, and Low Power Consumption
Donghwa Han, Bowhyung Lee, Min Jang +3
Block orthogonal sparse superposition (BOSS) code is a class of joint coded modulation methods, which can closely achieve the finite-blocklength capacity with a low-complexity deco…
Modeling and Coverage Analysis of K-Tier Integrated Satellite-Terrestrial Downlink Networks
Jungbin Yim, Jeonghun Park, Namyoon Lee
