Analysis of the rain outage performance of route diversity systems

摘要

Route diversity systems as available means to improve the rain outage performance are examined by comparison to tandem systems. A general and somewhat rigorous analysis for the evaluation of the joint probability on a pair of opposite hops has been performed, which is valid for any frequency. The total rain outage performance has been shown explicitly to be given approximately by the summation of joint probabilities on pair hops of the diversity system Finally, a general and compact algorithm for the evaluation of the path length enlargement effect has been constructed which is valid for any frequency, above 10 GHz and single hop-length of the corresponding tandem system.
