以信號特徵值為基礎之極微小基地台節能與降低干擾研究
Based On Fingerprint For Femtocell Power Saving and Reduce Interference Research
摘要
在下世代的通訊系統中，極微小基地台被提出解決細胞邊緣以及屋內的信號不足的問題，加上極微小基地台容易安裝的特性，預期在未來將會大量的被佈建，然而最顯而易見的問題就是在大量的佈建之下，能源的消耗以及基地台間的干擾。 所以在本論文，我們提出了一個可行且動態的極微小基地台節能且降低基地台間干擾的方法，藉由讓信號特徵值伺服器取得行動台和極微小基地台的信號特徵值，在合適的時候，讓極微小基地台進行狀態的轉換，經過我們的模擬結果，極微小基地台在使用我們的方法下可以大量的減少所花費的能源，且降低不必要的干擾，尤其在混合型極微小基地台的情況下，更加的明顯。

In next generation communication system,femtocell is proposed to slove weak signal problem in cell edge and house.Beacause femtocell is easy to install , it can be expected that femtocell will be a great amount of build.However, the obvious question is energy consumption and interference between base stations. In this paper, we propose a strategy to save energy and reduce base station to interfere another.Due to fingerprint server can acquire mobile station's fingerprint and femtocell's fingerprint , it will find the relation via comparison. Through this approach , we can change femtocell state in suitable timing. Based on simulation results, it can save lots of energy and avoid unnecessary interference from femtocell by our strategy.Especially in hybrid femtocell.
