Abstract :
According to the height of the flight platform, using a Markov process, switching between the Rice model and classic Loo model, is used to describe the ground-to-air fading channel. Each model is made to experience sight and severe shadowing states respectively. In order to improve the adaptability of the model, the Rice and Loo model are improved, and the Doppler power spectral density and probability density function of amplitude and phase of the two modified models are derived. The results of the simulation showed that the modified model of the Doppler power spectral density curve was an asymmetric shape, and the model adaptation is promoted, and it is clearly seen that the channels have different effects on signal transmission in different process and in different states.
