Simulation of the Effect of Fading Model on UHF Ground-to-Air Communication

The parameters of relative delay, relative amplitude and amplitude distribution in the fading model reflect the different fading characteristics of ground-to-air communication, and affect the effect of ground-to-air communication. Through the simulation test of UHF ground-to-air communication, the maximum communication distance under different fading model parameters and the output signal amplitude probability distribution function curve of wireless channel simulator are counted, and the mapping relationship between fading model parameters and output is established. When supported by the measured data, the measured signal can be compared with the probability distribution function curve from the simulation test, and the corresponding fading model parameters can be selected to improve the accuracy of the simulation test results.
