Site diversity is one of the advanced techniques that aim to mitigate propagation impairments affecting satellite communication (SatCom) systems operating above 10 GHz. In this work, we exploit two years of weather radar data collected at Johor (Malaysia) to simulate a site diversity SatCom system operating at 18.9 GHz with two links pointing to the WINDS satellite (elevation angle equal to 44°)....
A new frequency reuse scheme which reduces co-channel interference must be used to deploy over 20-GHz band fixed wireless access (FWA) systems in expanding service areas. Also, the capacity has become of primary importance in broadband wireless access (BWA) networks to provide multimedia services or other digital services requiring high capacity traffic channels. The co-channel interference and rain...
Link degradation due to rain fade is one of the obstacles in establishing the HAPS Communication services, mainly in the frequency above 10 GHz. As tropical rain is more localize in nature rather than wide spread. The site diversity is one of the effective solutions to limit the effect of rain fade in HAPS-Earth links to improve the systems availability. This paper examines the site diversity performance...
Local Multipoint Distribution Services (LMDS) is a terrestrial fixed radio technology for broadband communication applicable as point to multipoint wireless system operating at frequencies above 20 GHz. The most serious impairment at these frequencies is rain fading specially in the tropical areas. Many techniques could be used to overcome rain fading and applying Site Diversity as a possible solution...
