Geometric Characterization of LEO–GEO Inter‐Satellite Links for Bidirectional Communications
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Incorporating geosynchronous Earth orbit (GEO) and low Earth orbit (LEO) satellites can extend communication services far beyond the reach of terrestrial infrastructure. A key enabler of such architectures is the establishment of inter‐satellite links (ISLs) between LEOs and GEOs to support bidirectional communications.

ML‐Assisted Adaptive Fade Mitigation for Satellite Connectivity
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT The demand for reliable and high‐quality wireless networks driven by resource‐intensive applications and services is growing rapidly and invoked the emergence of beyond 5G (B5G) and 6G paradigm and technologies which include satellite systems as part of the nonterrestrial networks (NTN).

SMTC Configuration and Window Adjustment Strategies for Beam Hopping in NR‐NTN
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Beam hopping is an effective transmission strategy for nonterrestrial networks (NTNs), enabling satellites to allocate limited power and spectrum resources across different geographical regions over time. However, in NR‐based NTN systems, beam hopping complicates synchronization monitoring because synchronization signal block (SSB) arrivals ...

International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT The use of frequencies above 30 GHz (millimeter waves) for communication purposes is nowadays a necessity, both for terrestrial (e.g., 5G/6G) and satellite links. One reason is the need for more bandwidth and the fact that “traditional” frequency bands are already fully occupied.
