Optimal number of redundant channels for a digital communication system

Research output: Contribution to journalArticle

1 Scopus citations


In many critical applications of digital systems, fault tolerance has been an essential architectural attribute for achieving high reliability. This paper considers the problem of determining the optimal number of redundant channels in a digital communication system. The expected system cost is obtained. We determine the number of redundant channels minimizing the expected system cost. A numerical example illustrates the techniques.
