Path‐Based Deep Reinforcement Learning for On‐Board Routing in Satellite Constellation Networks

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Efficient usage of available network resources is a crucial factor for broadband services in interconnected satellite constellations. To meet required quality of service standards under heavy network loads, it is essential to optimize traffic distribution among the intersatellite links. To address this challenge, we propose an adaptive traffic

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

Integrating Semantic Communication and Human Decision-Making into an End-to-End Sensing-Decision Framework

IEEE Open Journal of the Communications Society
As early as 1949, Weaver defined communication in a very broad sense to include all procedures by which one mind or technical system can influence another, thus establishing the idea of semantic communication.

Multiple Access Design for Joint Semantic and Classical Communications

This chapter investigates the multiple access design for joint semantic and classic bit-oriented communications. For the resulting heterogeneous semantic and bit multiuser network, we discuss both orthogonal multiple access (OMA) and non-orthogonal ...

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 ...

Prescriptive Positivism: Discourse on Sustainable Development Goal Interactions and Perspectives for a Post‐2030 World

Sustainable Development, EarlyView.
ABSTRACT The Sustainable Development Goals (SDGs) are unlikely to be achieved by 2030, prompting debate about what should follow. Beyond revision, there is a need to critically examine what values and assumptions have shaped how the SDGs are conceptualised and operationalised.

Strategic Design Choices in Upcycled Fashion: Effects of Design Typicality and Material Domain Distance on Sustainable Consumption

Sustainable Development, EarlyView.
ABSTRACT While upcycling clothing reflects environmental value (i.e., greenness) and distinctive designs (i.e., uniqueness), consumer responses to upcycled clothing designs remain underexplored. Drawing on categorization, cue utilization, and domain distance theories, two experimental studies were conducted with US female aged 18–45.

Embedding Climate Action: Policy Integration and Semantic Coherence in Ireland's SDGs Policy Mix

Sustainable Development, EarlyView.
ABSTRACT Achieving the EU's 2050 target of climate neutrality requires embedding climate action (SDG13) within national sustainable development strategies. While inter‐governmental coordination and policy linkages are central to policy integration and coherence, existing studies rarely examine them in tandem.
