| dc.description.abstract | 本研究的目的在於探討利用高空飛機平台支援高速鐵路提供無線通訊服務的議題。由於高速移動所造成的都卜勒效應以及無線通道環境中多路徑干擾所造成的種種現象，皆使得在高速移動環境下的無線通訊困難度大幅增加。
然而因為飛機平台有良好的通道環境特性，例如：直視波存在、多重路徑的延遲變動較小、以及較小都卜勒漂移及都卜勒漂移變化率，所以我們希望能藉由飛機平台特殊且良好的通道環境，來支援高速列車，抵抗高速移動所帶來的種種影響。所以本論文針對飛機平台支援高速列車提供IMT-2000服務作一個完整的探討，並且針對系統的逆向鏈路系統容量做估算與安排，通過模擬可驗證設計的系統安排能有效地提升系統容量。此外也對於飛機平台與高速列車的環境提出換手程序上的修改與簡化，接著再引進可適性換手的概念，透過模擬的方式可以證實可適性換手的方式在飛機平台支援高速列車的環境下有較好的表現。最後，對於未來的研究方向提出建議 | zh_TW |
