Attenuation prediction for satellite propagation from point to point microwave link measurements

Abstract

This project will look into the prediction of satellite performance by analyzed and convert the summarized collected data on rain attenuation. The summarized data are taken from point to point microwave link measurements at Skudai, Johor Bahru, Alor Setar, Ipoh, Kuantan and Kota Bahru. The data needs to be taken into considerations on many aspects that will involve in wave propagation phenomena on the satellite points of view. The transformation of the data will then be used to predict the performance of the satellite propagation. As we can see, satellite communication has a very important function in the whole coverage area due to its several advantages compared to the terrestrial measurement. Reliability analysis is done by comparing the attenuation with the path attenuation calculated using ITU-R standard. The transformation of the measured point to point microwave link rain attenuation time series into satellite attenuation time series has been carried out. Thus, the prediction on satellite communications performance operating in Malaysia could be implemented by employing locally collected data.
