Abstract
The full-duplex relayed transmission is an expansion of relay technique. In this paper, we investigate an optimal power allocation strategy for the dual-hop full-duplex decode-and-forward (DF) relay system with joint constraint of individual and global power. We prove that the optimal allocation solution is located on the three boundary conditions of the constraint domain. The golden section search algorithm is used to obtain the highly accurate numerical solution of the optimal allocation strategy. Simulation results indicate that the optimal power allocation strategy enhances the outage performance.
