摘要: 
近幾年來 ,合作式網路已變成熱門的研究。其中兩種主要被討論的機制為放大傳送式以及解碼前送式。在本篇論文裡,我們研究在解碼前送式在不同使用中繼點的時機下平均頻譜效能以及平均速率並討論選擇中繼點對合作式網路的影響。我們利用適應性調變的技術在我們所設計的系統那不僅可以增加我們的頻譜效益外,還能使我們錯誤率低於某個我們需求之下。在機制一,我們能獲得最高的平均速率,但它的平均頻譜效能卻是最低的。相反的,在機制二下,我們能得到最高的平均頻譜效能,但平均速率是最低的。在機制一與二之間,我們發現另一個機制,他能獲得最好的平均速率,此外還能得到介於機制一與二之間的平均頻譜效能。此外,我們發現一個近似的規則。在這規則裡,我們只需知道每個通道間的訊雜比後,我們就能得到使用在不同傳輸使用適應性調變的結果。
