摘要

在本篇文章中，將介紹在長期演進技術(LTE)下，中繼站(Relay)的轉傳
技術中，比較放大轉發(AF)與解碼轉發(DF)在相同條件之下，彼此的中斷機率(Outage Probability)孰優熟劣。我們將分為三個時段，前面兩個時段，因為用戶並非同時傳輸給中繼站(Relay)，故將兩個用戶的傳輸時段拆開來看，而在第三個時段中繼站(Relay)將會把之前所收到的訊號在同時傳給彼此，來完成傳輸。在放大轉發(AF)跟解碼轉發(DF)的比較中，中斷機率是我們判斷傳輸效果的重點，在考慮前半段傳輸成功的情形之下，我們將兩種傳輸方案的干擾訊號與訊號噪音比(SINR)，帶入中斷機率(Outage Probability)的公式之中，得到我們所求的結果。

In this paper, we investigate the selection transmission scheme by two-way relaying for long-term evolution network. Our two-way relay using two kinds relaying protocol which are amplify-and-forward (AF) and decode-and-forward (DF). In our scheme, we consider asynchronous situation. We program the three time slot to deal with asynchronous circumstances. In the first time slot, one of users transmitted signal to relay. In the second time, another user also transmitted signal to relay. In the last time slot, relay would be chosen the amplify-and-forward (AF) or decode-and-forward (DF) transmission scheme by which has lower outage probability than the orther.
