Abstract
SummaryIn order to support future satellite broadcasting and communication in the Ka band and above, the time diversity method provides a novel attenuation mitigation technique for maintaining satellite service availability at levels between 99.9 and 99.99%. In this paper, the time diversity method is analyzed using various time delays from between 1 min and 1 h in an effort to mitigate convective rain attenuation by using various beacon signal transmission delays. For comparison purposes, receiver beacon data from Japan and Thailand are presented to highlight tropical and non‐tropical zone regional differences, and the International Telecommunications Union (ITU) R P.618‐12 standard is used for scaling up the Thaicom beacon frequencies from 12.57 and 12.59 GHz in the Ku band to 19.45 GHz, which is the Ka band frequency used by Japan's communication satellite (CS) beacon. We found that the time diversity method is very useful for mitigating the effects of rain attenuation. Copyright © 2016 John Wiley & Sons, Ltd.
