| dc.description.abstract | 在本論文中，我們分析了分碼多工系統中之快速功率控制在使用者以非常高速移動像是搭乘高速鐵路列車時之環境下的表現。透過一些分析以及模擬，我們發現隨著使用者移動速度上升，固定步階大小之快速功率控制誤差也會漸漸增加。對此，我們首先討論不同速度下的最佳步階大小，並利用了快速功率控制近似於delta調變器的性質建構了一個可適性步階大小之功率控制演算法，接著我們也建構了一個預測性的功率控制演算法，並將此法與可適性步階大小做結合，而透過模擬實驗的結果我們發現，當通道環境為有直視波之高速鐵路環境時，結合可適性步階大小之預測性功率控制演算法對於功率控制的誤差的確有一定程度的改善。 | zh_TW |
