Outage and capacity analysis of cascaded diamond shaped cooperative relay network

Abstract

This paper gives the performance study of a cascaded diamond network. A route that provides the maximum of minimum value of available SNRs of all paths is elected. At first, the cumulative distribution function (CDF) of the overall SNR of the considered system is found. By using the derived CDF, the outage probability, coding and diversity gain of the considered system are derived. Later, ergodic capacity of the cascaded diamond network is also found. It is shown that the considered system is having a diversity order of two. Finally, numerical outcomes are posed to discuss the performance of the system.
