Low‐Complexity Hybrid Beamforming for LEO Satellites: Beam Update Rate Analysis and Advanced Adaptive Precoding

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Low Earth Orbit (LEO) satellite constellations offer unprecedented opportunities for global broadband connectivity but pose significant beamforming challenges due to rapid platform motion and stringent onboard hardware constraints. Fully digital architectures, while optimal in theory, remain impractical for satellite payloads, motivating ...

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 ...

Restoring End‐to‐End Transport With QUIC on Satellite Paths

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Slow Start is a key congestion control mechanism used to assure a safe response to overload of a path across the Internet. This mechanism increases the startup time taken by the sender to reach the capacity available across the path. The benefit becomes significant on paths with a high bandwidth‐delay product.

Phasing Out Coal Power Through Cross‐Border Renewable Energy Trade in the Asia‐Pacific

Sustainable Development, EarlyView.
ABSTRACT Coal remains the backbone of electricity generation in the Asia‐Pacific region, accounting for half of total regional output and two‐thirds of global coal‐fired capacity. The substantial environmental and public‐health externalities of coal highlight the urgent need to accelerate the renewable energy transition.

Can Digital Finance Drive Green Growth and Sustainable Development? Evidence From 118 Countries Across Development Status and Crisis Contexts

Sustainable Development, EarlyView.
ABSTRACT This study investigates whether and under what conditions digital finance advances green growth (GG) and broader sustainable development (SD) objectives in a financially volatile, climate‐constrained, and developmentally unequal world. Using annual data for 118 developed and developing countries from 2004 to 2022, we construct four Principal ...
