In these systems, a source node can communicate with a destination node directly or via the selected relay nodes, while relay nodes harvest energy from radio frequency for forwarding the received signal. In addition, the decode and forward (DF) protocol is applied to relay nodes, and selection combination technique is employed at the destination in order to select the best relay node. The system performance is presented by outage probability expressions over independent and identically distributed () Nakagami-m channel model. The theoretical analysis and the closed-form expression of outage probability are derived and compared with Monte-Carlo simulations. The simulation results are similar to the theoretical analysis results, it verifies our proposed derivation method. |
