In this study, the authors study an energy harvesting relaying system with multiuser, in which the relay node is capable of harvesting radio‐frequency energy and retransmitting data with harvested energy by employing the power splitting strategy. The joint impact of direct and relaying links is taken into account in the process of user selection, and furthermore exploited for data transmission by using the selection combing receiver. To evaluate the system performance, analytical outage probabilities regarding both amplify‐and‐forward (AF) and decode‐and‐forward (DF) relaying have been derived under Rayleigh fading channel. Furthermore, they calculate the asymptotic expressions of outage probability, and they confirm that AF relaying as well as DF relaying approaches the system diversity order of N + 1 , where N denotes the user number. Numerical results are demonstrated to validate the proposed analysis as well.
