Abstract: Based on the N-State Markov chain model established by Markov theory, the rain attenuation time series about Changchun and Xinxiang areas are simulated and the complementary cumulative distributions obtained by the simulatived and measured data at these areas are compared.The probability distribution about 50 simulative rain attenuation time series are compiled in statistics.The results agree with the results predicted by ITU-R model at 12.5 GHz and 92°Eorbital position of the geostationary satellite.Hence,the usability of this model is validated at partial areas in China.This research establishes a basis for the development of the rain fade mitigation techniques in communication and radar systems at Ku and above Ku band.
