摘要：

This letter investigates the error rate performance of simultaneous wireless information and power transfer-based differential amplify-and-forward relaying in the presence of Nakagami-m fading and a direct link. We provide a closed-form expression for the probability density function of the signal-to-noise ratio (SNR) of the two-hop (TH) link based on a high SNR approximation. Novel closed-form approximate average bit-error rate expressions are derived for both the single TH scenario and the scenario with a linear combiner for the TH link and a direct link. The impacts of different values of the fading parameter m on error rate performance are also investigated. Analyses are verified through Monte Carlo simulations.
