The upcoming migration of satellite services to higher bands, namely the Ka- and Q-bands offers many advantages in terms of bandwidth, data rates and system capacity. However, it poses challenges as propagation effects introduced by the various atmospheric phenomena are particularly pronounced in these bands and can become a serious constraint in terms of system reliability and performance. This paper...
The need for increased data rates has led towards the development of advanced broadband satellite systems able to achieve higher capacity for providing Internet and backbone services in remote areas. Aside of the more conventional geostationary orbit (GEO), Medium Earth Orbit (MEO) satellite constellations are envisaged due to their advantages in terms of shorter link path and low latency; MEO satellite...
The ongoing migration of satellite communication services to higher bands, namely the Ka- and Q-bands offer numerous advantages; however, signal propagation at these bands can be severely impaired by the various atmospheric phenomena. To assist in the validation and development of new accurate propagation models in these bands, two propagation site diversity experimental campaign have been initiated...
The reliable design of modern satellite communication systems operating above 10GHz requires the accurate evaluation of the channel modeling. Rain attenuation is the dominant fading mechanism for satellite links at Ku, Ka and Q/V band. Channel modeling is also important for the optimum design of the Fade Mitigation Techniques (FMTs). In this paper we present annual, seasonal, and diurnal simulated,...
This paper provides a new stochastic model for the calculation of cloud attenuation time series for Earth-space links at optical frequencies. The presented methodology is based on the employment of stochastic differential equations for the generation of time series of cloud fields. More specifically, we propose a dynamic stochastic model for the evaluation of Integrated Liquid Water Content (ILWC)...
