Comparison of tropospheric scintillation prediction models of the Indonesian climate

Abstract

Tropospheric scintillation is a phenomenon that will cause signal degradation in satellite communication with low fade margin. Few studies of scintillation have been conducted in tropical regions. To analyze tropospheric scintillation, we obtain data from a satellite link installed at Bandung, Indonesia, at an elevation angle of 64.7°and a frequency of 12.247 GHz from 1999 to 2000. The data are processed and compared with the predictions of several well-known scintillation prediction models. From the analysis, we found that the ITU-R model gives the lowest error rate when predicting the scintillation intensity for fade at 4.68%. However, the model should be further tested using data from higher-frequency bands, such as the K and Ka bands, to verify the accuracy of the model.

“…Besides basic physics, a wealth of such data provides an opportunity to statistically characterize radio channels for communication purposes. Based on such data, researchers have proposed models of rain attenuation, scintillation, and site diversity predictions . These models enable development of efficient PIMTs to mitigate disruptions in respective radio channels.…”

“…It could also be seen that the pdf has a positive skew for a long-term observational period, especially for the strongest intensities. This should be expected due to the absence of rain as a result of the cumulus clouds that lead to a burst of strong scintillation during the event of cumulus clouds across the path [10]. The information from the pdf scintillation amplitude may assist to derive the probability of average biterror on the scintillation-fading digital satellite link in the region [13], [22].…”

“…A small integration time of 1 Hz is chosen to sufficiently characterize troposphere scintillation as reported in the work of Cheng and Mandeep [10]. The 0.6 m offsetted parabolic dish antenna of the beacon measurement was fixed upon a pole in a fenced area besides Physics building of the University.…”

“…Based on their results, the Karasawa and Ortgies-T models were found to have the best overall performance in the region. Cheng and Mandeep [10] also analyzed tropospheric. Scintillation based on data from a satellite link installed in Bandung, Indonesia, at a frequency of 12.247 GHz from 1999 to 2000.…”

“…Hence, generalizing signal degradation arising from the clear-air effect may either underestimate or overestimate the link budgeting needed in the design of satellite communication systems. Although this paper used the method earlier adopted by [6] and [10], the differences lie in the usage of the entirely new measurement site with different meteorological parameters, different years of measurements, different satellite look angle and the type of rain gauge used. The subject matter has also started receiving attention in Nigeria.…”
