| Summary: | 碩士 === 國立中央大學 === 通訊工程學系 === 107 === This paper discusses the outage performance of full-duplex relay channel using amplify-and-forward(AF) relay protocol with energy harvesting(EH) and compare with its optimum one. Previous works almost focused on that destination treated the self-interference signal as interference only, so in that works they wanted to eliminate self-interference(SI) signal. We provide a system model with make self-interference signal assist information decoding at the destination. At the relay node, the received signals, including self-interference, are split according to a power ratio for information processing (IP) and energy harvesting, respectively. We derive an approximate, yet accurate, closed-form expression for the end-to-end outage probability and optimum one. In addition, the processing delay is larger than one in practice, the proposed close-form outage probability expression is still valid. Finally, we corroborate our theoretical results with simulations in different situations. The results indicate that the proposed system model with optimization can outperforms system with fixed power splitting method.
