Dr. Sandro Scalise
A good understanding of the impairments introduced by the propagation channel is of paramount importance in the design of a satellite-based communications system. The relevant sources of channel impairments depend upon several factors, among them the considered scenario (e.g. mobile vs. fixed terminals, rural vs. urban etc…), the carrier frequency and the employed access scheme. For instance, effects like shadowing and blockage are typical of mobile reception. On the other hand, atmospheric attenuation phenomena can be safely disregarded at frequency bands below some GHz, whereas they start to become relevant as the carrier frequency increases.
Each of the main parts of this lecture will be organized as an independent module. In general, the main focus will be on specific results and considerations derived by models and measurements, rather than on reviewing the well-known theory of channel characterization and modelling. Nevertheless, the most important definitions will be recalled for the sake of clarity and adequate references provided.
