| Abstract(in English) | The most serious transmission impairment is caused by the rain attenuation in the radio systems using friquencies above 10 GHz. So, in the system design, it is required to estimate the rain attenuation distribution in the area under consideration. It has been considered that the rain attenuation should be estimated by using measured 1-minute-rain rate distribution. In Japan, the Gamma distribution is used on terrestrial links and Log-Normal distribution is used on satellite links. But both distributions have significant errors if wide cumulative probability region is considered. Moupfouma distribution which result in good approximation in wide cumulative probability region was proposed by Moupfouma in order to solve this problem. But there are few examples which applied Moupfouma distribution to worldwide data. This method is investigated to be applied worldwide by using deta bank which osists of 82 data sets from 22 countries. In investigation, M distribution is also used as simple approximation of Moupfouma distribution. |
