Modeling of First-Order Statistics of LMS Channel under Tree Shadowing for Various Elevation Angles at L-Band

Popis výsledku v původním jazyce

In this paper, the first order statistics of co-polar components for a Land Mobile Satellite (LMS) channel for two scenarios, are investigated. The two scenarios refer to tree shadowing, one with the receiver placed inside an alley of trees and the second one with the receiver placed outside this alley of trees. For these two scenarios the received power for two orthogonal co-polar components was measured at Stromovka Park of Czech Republic using an airship. Due to the significance of first-order statistics of the signal envelope, using the measured power, four distributions are evaluated. More particularly, the Loo, Rice, Rayleigh and Lognormal distributions are investigated for modelling the Cumulative Distribution Function of the signal envelope forvarious elevation angles. It is found that Rice and Loo distributions have a very similar behaviour, while Rayleigh has the worst performance. Finally, some useful conclusions are drawn.
