Evaluation of multi‐user multiple‐input multiple‐output digital beamforming algorithms in B5G/6G low Earth orbit satellite systems

International Journal of Satellite Communications and Networking, EarlyView., 2023
In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such

Uncovering ESG Ratings: The (Im)Balance of Aspirational and Performance Features

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Environmental, Social, and Governance (ESG) scores are crucial for evaluating corporate sustainability. However, the undisclosed and complex methodologies used by rating agencies have raised concerns about their reliability and consistency. This study replicates LSEG's ESG scoring methodology using machine learning to shed light on the key ...

HETEROGENEOUS SUBSCRIBERS AND THE OPTIMAL TWO-PART TARIFF OF TELECOMMUNICATIONS SERVICE

, 1992
In this article, optimal two-part tariffs of a bi-directional telecommunications service are exam­ ined. Heterogeneous users are assumed to formulate social demand for the service. Two regimes of supplier are considered: monopoly and non-monopoly. In the

Internet of Things (IoT) and the Environmental Sustainability: A Literature Review and Recommendations for Future Research

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT As the Internet of Things (IoT) surges forward, intersecting with an urgent demand for environmental sustainability (ES), digital technologies emerge as potent orchestrators of systemic transformation. Employing a subtle blend of bibliometric‐systematic literature review (B‐SLR) and qualitative insights, this research investigates IoT's ...
