Preprocessing Procedure for Propagation Measurements on MEO Satellite Links
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT This paper presents a software tool designed for preprocessing data from an experimental campaign aimed at characterizing the tropospheric propagation channel using Medium Earth Orbit (MEO) satellites. The collected data provide critical insights into the channel in scenarios involving continuous variations in azimuth and elevation, along with

Performance of multiple-input multiple-output wireless communications systems using distributed antennas [PDF]
, 2005 In this contribution we propose and investigate a multiple-input multiple-output (MIMO) wireless communications system, where multiple receive antennas are distributed in the area covered by a cellular cell and connected with the base-station (BS).

On the Impact of Mobility on Outage Probability in Cellular Networks [PDF]
2009 IEEE Wireless Communications and Networking Conference, 2009 In this paper, we develop an analytical study of the mobility in cellular networks and its impact on quality of service and outage probability. We first express analytically the downlink other-cell interference factor f by using a fluid model network. It is defined here as the ratio of outer cell received power to the inner cell received power.

Sustainable Development, EarlyView.ABSTRACT The increasing exposure of global supply chains to environmental, social, and operational disruptions has intensified scholarly interest in sustainability and resilience. While these concepts are widely discussed, existing research often addresses them separately, preventing understanding of their combined role in supply chain management.
