This study introduces an innovative approach for adaptive power allocation in Non-Orthogonal Multiple Access (NOMA) systems, enhanced by the integration of spaceborne and terrestri…
Iterative Sparse Identification of Nonlinear Dynamics
Jinho Choi
In order to extract governing equations from time-series data, various approaches are proposed. Among those, sparse identification of nonlinear dynamics (SINDy) stands out as a suc…
Enhancing Reliability in LEO Satellite Networks via High-Speed Inter-Satellite Links
Jinho Choi
Low Earth orbit (LEO) satellites play a crucial role in providing global connectivity for non-terrestrial networks (NTNs) and supporting various Internet-of-Remote-Things (IoRT) ap…
Wireless Distributed Matrix-Vector Multiplication using Over-the-Air Computation and Analog Coding
Jinho Choi
In this paper, we propose an over-the-air (OTA)-based approach for distributed matrix-vector multiplications in the context of distributed machine learning (DML). Thanks to OTA com…
