Abstract

The aim of this paper is to design and evaluate hop calculations and system performance for line of sight (LOS) radio relay links utilizing a simplified proposed procedure. Such a procedure is simulated for the determination of both hop calculations and system performance. The practical procedure of this paper has been ordered in a manner to solve up to 95% of the hop design problems encountered in practice. Two examples with different specifications and different required outage time are examined to fulfill the Committee Consultative International Radio (CCIR) recommendations.
