| Abstract: | A lot of work has been focused on designing and analyzing various cooperative diversity protocols for wireless relay networks. To provide a unified queuing analytic framework, we formulate an embedded Markov chain, which turns out to be a Quasi-Birth-and-Death (QBD) process. Using the Matrix-Geometric method, we can analyze the average delay in a unified way. Theoreti-cal analysis is validated by simulation results. We show that the delay performances of Amplify-and-Forward or Decode-and-Forward (AF/DF) and incremental AF/DF schemes can be analyzed in the unified way. Thus, we can always choose the best cooperative diversity scheme in different scenarios for delay minimization. |
