ANALYSIS OF RELIABILITY CONSIDERATION TO OBTAIN AN ERROR FREE COMMUNICATION OVER A LONG HAUL DIGITAL MICROWAVE LINK

Abstract

In the system design of a digital microwave link the designer must be ensure that the link satisfies the regulatory requirement, it is compatible with the digital hierarchy and the link performs the well over a long path of communication system. Ideally, the performance of a digital microwave link is independent of the number of repeaters and the system length and topology. But in reality, transmission quality is not completely independent of length of the system or the number of the repeaters. The major factors, which affect the transmission qualities, are: multipath propagation, Rainfall, anomalous propagation disturbances, reflections etc. In this paper analysis of the reliability consideration has been carried out to obtain an error free communication over a long haul digital microwave link.
