Power Allocation in Coded Cooperation Systems with Convenient Cooperation Ratio

The problem of power allocation in networks which used cooperative diversity schemes whether AF (Amplify and Forward) or DF (Detect and Forward), has been studied in the literatures, however in the coded cooperation scheme, power allocation has not been investigated yet. In this paper we investigate power allocation in the coded cooperation system. We will propose simple and sub optimum power allocation based on our analytical results. Also we will provide suboptimum cooperative ratio in the proposed algorithm. Finally high performance of our proposed suboptimum power allocation will be shown in simulation.
