Enhancing LEO direct-to-satellite channel modeling with the shadowing effect via K-distribution

Accurate channel modeling is crucial for optimizing direct-to-satellite Internet of things (DtS-IoT) communications via low Earth orbit (LEO) nanosatellites. Traditional channel models for land-mobile satellite systems often overlook the significant impact of shadowing at low elevation angles, limit...
