Method for establishing channel simulation model meteorological composite channel under cloudy weather conditions

The present invention discloses a method for establishing channel simulation model meteorological composite channel under cloudy weather conditions, comprising (a) Analysis of shadowing effects clouds cloudy weather conditions meteorological signals and multipath effects, the theoretical analysis given receiver signal envelope function and a probability density distribution function of the error rate limit; (ii) the results of the analysis in step (a) establishing meteorological composite channel simulation model. The present invention is directed to the clouds in cloudy weather conditions on the composite effect problem meteorological satellite communications, meteorological research complex channel characteristics, and by theoretical analysis and modeling simulation can qualitatively to the static statistical properties of the composite weather satellite channel proved the theoretical analysis correctness and validity for the study of meteorological satellite communications system performance and optimization of meteorological satellite communications system provides a certain technology base.
