摘要: [1] This research examines route diversity as a fade mitigation technique in the presence of rain for convergent, terrestrial, microwave links. A general model is derived which predicts joint distribution attenuation on arbitrary pairs convergent links, directly from link parameters. It assumed that links have distributions are bilognormally distributed. Four five parameters can be estimated International Telecommunication Union recommendation models. maximum likelihood estimation method was used previous paper to estimate fifth parameter, is, covariance or correlation. In this an empirical reported, linking correlation log with geometry and radio pair From these distributions, advantage due may calculated margins. Furthermore, predicted statistics vary smoothly yield plausible extrapolations into low-probability scenarios. Diversity improvement set example
