Overview physical layer technologies low-Earth-orbit Project Details
| Abstract |
This research project offers a full evaluation and simulation framework for the physical‑layer technologies used in today’s Low‑Earth‑Orbit (LEO) broadband satellite systems. Drawing inspiration from commercial constellations such as Starlink, Kuiper, and OneWeb, the study looks at how terrestrial standards—like 5G Non‑Terrestrial Networks (NTN) and Direct‑to‑Cell LTE—can be adapted to the fast‑changing satellite environment. Key physical‑layer issues are examined, including large Doppler shifts, long propagation delays, and path loss that varies with time. The approach models the entire transmission chain, covering advanced modulation formats, channel coding, and beamforming methods designed for LEO orbits. Systematic simulations assess link‑budget performance, bit‑error‑rate (BER) behavior, and spectral efficiency across different orbital altitudes and elevation
angles. The work also investigates how 3GPP Release 17/18 standards and upcoming 5G‑Advanced/6G physical‑layer enhancements can be integrated. Overall, the research provides a clear guide to the merging of terrestrial and non‑terrestrial networks, giving design insights and performance benchmarks for next‑generation satellite broadband architectures.
