Average outage duration of multihop communication systems with regenerative relays

Abstract

Closed-form expressions for the average outage duration of multihop regenerative communication systems over generalized fading channels are presented. These results are general and account for the noise-limited and interference-limited systems. To show the usefulness of the presented expressions, some specific fading scenarios are considered. Finally, some numerical examples of interest comparing direct and relayed transmission, and studying the effect of increasing the number of hops and/or co-channel interferences are plotted and discussed.
