Abstract

This paper presents estimation of tropospheric scintillation based on ITU-R model from previous 10 years meteorological data. Scintillation A_s(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 N_wet. 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.
