Performance Analysis of Satellite-HSDPA Transmissions in Emergency Networks
نویسندگان
چکیده
In this work we are interested to investigate how the Geostationary (GEO) satellite can be used to employ efficiently High Speed Downlink Packet Access (HSDPA) technology supporting Multimedia Broadcast/Multicast Service (MBMS) in a scenario in which the terrestrial network is not available. An exhaustive simulation campaign has been carried out with the aim to determinate the Satellite-HSDPA (S-HSDPA) performances in different radio channel conditions. In particular, a Good/Bad Channel model has been taken into account to achieve a specific radio information and to be able to evaluate the maximum date rate that can be obtained by S-HSDPA.

متن کاملEstimation and Analysis of Precipitable Water Vapor Using GPS Data and Satellite Altimeter
Determination of water vapor in the atmosphere plays an important role in forecasting weather conditions and precipitation studies. For this reason, it is very important to study the tropospheric delay, especially the wet component, which is due to the presence of water vapor in the atmosphere. In this paper, the amount of water vapor was estimated by altimeter satellite radiometer and GPS data...
