Abstract :
In this comment, we give a detailed proof to get the power allocation solution for an amplify-and-forward cooperative communication system with n relay nodes, which is based on analyzing. Our conclusions show that the solution with "+" sign is optimal although the solution with "-" sign is also valid for equations (41) and (42) in.
