| Abstract: | Studies are presented on five radio propagation models in ITU-R recommendations. The models include statistical prediction method for tropospheric scatter transmission loss, prediction method for sea reflection fading in maritime mobile satellite telecommunications, conversion method for ionosphereic scintillation fading, simplified prediction method for attenuation by atmospheric gases and modified prediction method for field strength in land mobile services. |
