dc.description.abstract	當IEEE 802.11在一個錯誤位元率(BER)不斷上升的通訊通道中, 一個長的訊框通常在傳送及接收方面會有比較低的成功機率. 而定義在IEEE 802.11 MAC中的Fragmentation正因上述狀況而存在, Fragmentation雖然可以改善封包遺失(packet loss)的問題, 但不幸的也同時使得封包延遲(packet delay)和通道的吞吐量(throughput)也大幅下降. 在此篇論文提出一個名為組合式傳送方法, 該方法相容於舊有IEEE 802.11 MAC並且當系統工作在一個帶有雜訊的通道中可同時改善封包遺失、封包延遲以及通道吞吐量. 相對於謀體控制層(MAC-Level)中效率比較低的停等重傳(Stop-And-Wait ARQ), 在組合式方法中可以引入更具有效率之訊框層(Frame-Level)的選擇性(Selective Repeat)和多次複製(Multi-copy)重傳方法來改善重傳的效能. 最後透過數據分析(Numerical Analysis)和模擬(Simulation)來證明當IEEE 802.11工作在帶有雜訊的通道中此方法可同時有效改善封包遺失、封包延遲和通道吞吐量.	zh_TW
