Autor: Dario Tagliaferri, Andrea Matera, Carlo Capsoni, Umberto Spagnolini

Publikováno v: IEEE Photonics Journal, Vol 10, Iss 4, Pp 1-14 (2018)

In this paper, we consider a multiuser multiple-input-single-output (MU-MISO) downlink visible light communication (VLC) system deployed in airplane cabins, for serving high-speed Internet to the passengers through the reading lamps. The high number

Istical Characterization of Aerosols' Liquid Water Content and Visibility for Terrestrial FSO Links

Autor: Muhammad Saeed Khan, Roberto Nebuloni, Martin Grabner, Carlo Capsoni, Erich Leitgeb, Vaclav Kvicera

Publikováno v: Communications, Vol 14, Iss 2, Pp 27-32 (2012)

Liquid water content (LWC) is a microphysical parameter which is used to characterize fog/cloud and other particulates. In the absence of precipitation higher amount of LWC depicts dense fog, significantly reducing visibility and causing performance

On the Accuracy of Simplified Models for Water Vapor Attenuation Prediction at Ka band and Q band

Autor: Carlo Riva, Lorenzo Luini, Carlo Capsoni

The accuracy of the approximate prediction models included in recommendation ITU-R P.676 aimed at estimating the attenuation due to gases (water vapor and oxygen) from ground meteorological inputs is assessed. To this aim, the gaseous attenuation der

Elevation scaling of rain attenuation time series

Autor: Carlo Capsoni, Lorenzo Luini, L. M. Tomaz

In satellite links, the variations in the elevation angle have a strong impact on the magnitude of the attenuation induced by rain because the path-length across precipitation increases with the decrease in the elevation. In particular, it is definit

Characterization of Indoor Visible Light Communication Channels and Design of a DCO-OFDM System

Autor: Carlo Capsoni, Dario Tagliaferri

Publikováno v: 2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC).

This paper reports the implementation of a DCO-OFDM transceiver apt for indoor visible light communication scenarios, with particular emphasis on the sampling clock synchronization issue. Starting from the characterization of a typical indoor VLC cha

Scaling Rain Attenuation as a Function of the Link Elevation

Autor: Carlo Capsoni, Lorenzo Luini, L. M. Tomaz

The effect of the attenuation due to rain in satellite links increases rapidly for frequencies above 10 GHz. The development of tools to mitigate this impairment relies on the good knowledge on the behavior of the rain attenuation, and in particular
