Average bit error probability analysis for cooperative DF relaying in wireless energy harvesting networks

Abstract

Thanks to the benefits of energy harvesting (EH) in cooperative decode-and-forward (DF) relaying networks, we decided to consider a CRN deploying time-switching based relaying protocol (TSR) to study EH. To clearly evaluate the system performance, we derive the expressions for outage probability at high end-to-end signal-to-noise ratio (SNR), ergodic capacity, and the average bit error probability (ABEP). After finishing the performance analysis, we provide Monte-Carlo simulations to prove the performance and the correctness of the obtained numerical results.
