在本論文中，我們利用雙路徑放大前送(amplify and forward)中繼的方式來提升合作式網路的資訊傳輸率，並且利用Alamouti編碼設計及其解碼接收機制以降低傳輸錯誤率。針對其中雙路徑架構所造成Alamouti編碼失去正交性的問題，我們將提出解決方案。此外，我們也討論在雙路徑架構裡兩個中繼間互相干擾(inter-relay interference)的議題，並尋求解決方法。最後也探討傳送功率設計及分析中繼站在網路中位置的影響。

In this thesis, we present a transmission for amplify-and-forward two-path relaying with Alamouti code. However, we solve the problem that the Alamouti code loses the orthogonality as we transmit in two-path relay structure. In particular, we focus on the cancellation of inter-relay interference and detection scheme. Finally, the issue of power allocation and relay position are also included.
