摘要(中)

在本篇論文中，主要針對能量採集和無線能量蜂巢式網路架構下做討論，能量採集是近年興起的技術，因為通訊裝置的能量有限，所以延長使用時間變得很重要，能量來源是從環境來的，也具環保意義，如：風力、太陽能、震動，而最近能量來源為射頻訊號受到熱烈討論，這也是這篇論文所採用的能量來源。無線能量蜂巢式網路有一個多天線存取點(AP)作為能量傳遞，多個使用者則做資料傳輸，下行時間能量傳遞，上行時間資料傳輸。

摘要(英)

Traditionally, energy-constrained devices are powered by fixed energy sources. But it will run out one day. It’s important to extend the lifetime by recharging. Energy harvesting is a solution, it has emerged recently since it provides power supplies from the environment. Radio-frequency(RF) signals become a source for energy harvesting. We consider a Wireless-Powered Cellular Network including an access point and numbers of users. The AP broadcasts wireless energy to users in the downlink, then users transmit information to AP in the uplink.
