Performance of Mixed Shadowed Ricean/TWDP Relayed Assisted Link

In this paper, we consider the inclusion of Low-Earth-Orbit (LEO) satellites in the terrestrial mobile network. We study the transmission of information from a LEO satellite to a mobile terminal on the surface of the Earth. Signal transmission is performed with help of a relay on Earth that applies a decode-and-forward (DF) strategy. For the channel from the satellite to the relay, a channel model is used that includes multipath propagation, where there are one dominant and many non-dominant components, where both the dominant and non-dominant components are under the influence of the shadowing effect. After decoding in the relay and amplification, the signal is further transmitted in the millimeter range to the mobile terminal. A numerical procedure for calculating the outage probability is developed, and then an analysis of the influence of the parameters of both channels on the outage probability is performed.
