Modeling and Simulation of UHF Satellite Mobile Communication Channel

The fading characteristics of UHF satellite mobile channel is analyzed.The Doppler spectrum expression and the multipath delay spectrum expression of multipath components in four typical scenes are analyzed.On the basis of WSSUS(Wide-Sense Stationary Uncorrelated Scattering) model,the channel models of four scenes are built considering the degree of scintillation and shadowing.With theory computation and related references,the parameters of different channels are analyzed and the satellite mobile channel models are simulated.In the end,the bit error rate performance curves are given.The simulation results show that the proposed channel model can truly reflect the characteristics of UHF satellite mobile channel.The model in this paper is of guiding significance in exploration and research of satellite mobile communication.
