Abstract :
Differential Amplify-and-Forward (DAF) relaying can be viewed as an attractive cooperative communication strategy for wireless networks where channel estimation is not feasible or it is rather avoided. A new exact outage probability expression is presented herein for DAF relaying that involves only a single integral. Then, an asymptotically tight closed-form approximation is obtained which enables power allocation optimization for the outage behavior of DAF relaying. Numerical and simulation studies validate the theoretical analysis.
