Routing and Downlink Resource Allocation for Multicast Traffic in LEO Satellite Constellations

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT In this work, we optimize unicast and multicast traffic delivery over non‐terrestrial networks (NTNs) to users on the ground through direct satellite downlink (DL). We consider a gateway‐free mesh architecture with low Earth orbit (LEO) satellites interconnected via inter‐satellite links (ISLs), where unicast and multicast services compete for

Long‐Term Propagation Measurements in Madrid in a Q‐Band Satellite‐to‐Earth Link

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The Q/V band (40/50 GHz) is gaining interest as satellite operators will need larger bandwidth to be able to provide their services, which are experiencing an increasingly high demand. An accurate characterization of the satellite‐to‐Earth propagation channel is of paramount importance to guarantee a high level of quality of service, by ...

Competition Policy and Achieving Sustainable Development Goal 1 (No Poverty): The Role of Mergers and Acquisitions Adjudications in South Africa

Sustainable Development, EarlyView.
ABSTRACT South Africa faces persistently high poverty and inequality alongside a highly concentrated economic structure, raising questions about whether merger control, especially public‐interest provisions, can contribute to poverty reduction. However, empirical evidence directly linking merger adjudication outcomes to poverty remains limited.

Opportunities for Australia Amid China's Carbon‐Neutral Transition: Input–Output Approach With Analysis of Australian Renewable Potential

Sustainable Development, EarlyView.
ABSTRACT A major transformation in China's energy mix is underway as the country pursues carbon neutrality by 2060, posing significant structural challenges for Australia as a major exporter of carbon‐intensive resources. This study examines the economic impacts of China's decarbonisation on Australia by applying static and dynamic input–output (IO ...
