Wirelessly Energy Harvesting DF Dual-hop Relaying Networks: Optimal Time Splitting Ratio and Performance Analysis
Abstract
This paper is to derive the optimal time splitting ratio for wireless energy harvesting DF dua-hop relaying networks. Using the partial relay selection, the best relay having the largest harvesting energy is chosen to be the forward for the second hop. We also derive the closed form expression for the optimal time splitting ratio that maximizes the system instantaneous capacity. Numerical results have shown that the system with the optimal time splitting ratio can significantly improve instantaneous and ergodic system capacity at high signal-to-noise ratios for the same channel and system settings.
