Аннотация
This paper presents a refined model of the flat fading stochastic process in satellite communication channels caused by multipath propagation when using narrowbeam receiving antennas. The key improvement over prior model lies in a reparameterization that explicitly accounts for the main lobe of a typical antenna radiation pattern, following ITU-R recommendations. For the proposed model, we derive expressions for level-crossing rate and average fade duration. The simulation of DVB-S2X VL-SNR signal propagation over fading channel based on derived model was performed, which demonstrates negligible loss in error resilience under fading depths most frequently observed in practice.
