Abstract :
This paper presents estimation of tropospheric scintillation based on ITU-R model from previous 10 years meteorological data. Scintillation As(p) is critical in designing of microwave links for achieving optimal performance. There are many phenomenons that cause degradation to signal during transmission through the earth´s atmosphere one of them is scintillation. Scintillation estimation is based on measurements of surface temperature T and relative humidity RH. Input parameter for ITU-R scintillation estimation model is the monthly average of wet part of refractivity Nwet. MATLAB software tool is employed to show the results for tropospheric scintillation in various seasons for time percentage p and frequencies ranging from 4GHz to 20GHz.
