This paper considers a non-linear energy harvesting (EH) model, better reflecting the properties of practical circuits compared to the linear model, in an amplify-and-forward (AF) relaying network. We focus on the design of relay's power splitting scheme to optimize the system outage performance, and derive the optimal power splitting ratios with both perfect and imperfect channel state information (CSI), respectively. Using the dynamic power splitting scheme, we find that the system outage performance is enhanced in the low signal-to-noise ratio (SNR) regime while converging to an upper bound in the high SNR regime. This finding is significant since it illustrates that the nonlinearity of practical energy harvester brings changes to the design of relaying networks. Simulation results are provided to support our work.
