摘要
In the design of long haul radio relay links using frequencies above 10 GHz, it is necessary to estimate outage time occurrence probability due to rain attenuation for multirelay systems. A theoretical predictive method is proposed in this paper which is involved with the analysis of joint attenuation exceedance probabilities using a very simple exponentially shaped spatial rainrate profile. This same rain structure model has been originally developed for the prediction of rain attenuation of microwave satellite links. Numerical results have been obtained and compared with experimental data taken from a multirelay system located in Japan.
