... is given in Appendix B.Now, we are deriving the SER expression for the selectionrelaying scheme discussed in Section 3. Averaging overconditional SER in (23), we have the exact SER expressionasP e (R)=∞0P e R ... allocation strategies are designed for highSNR scenarios, we study the system performance in the highSNR regime. Furthermore, since we supposed that the relaysare operating in low noise conditions, ...
