無線通訊所需傳送的資料量越來越多,所以如何在越短時間內傳送相同資料量是重要的研究主題。兩終端節點藉由中繼節點傳送訊號至彼此的雙向中繼網路為近年來熱門的研究,而利用實體層網路編碼的兩階段雙向中繼網路更是一種高頻譜效益的技術。數個使用相差相位調變的兩階段雙向中繼網路架構被提出,這些架構可以避免由前導符元導致的速率損失。

在本篇論文中,我們首先探討及比較數個單一中繼節點的放大轉傳與解碼轉傳架構。於放大轉傳架構下,我們指出兩種定義的正規化因子之差異;於解碼轉傳架構下,我們發現若兩個終端節點使用相同星座圖,中繼節點使用非同調多重符元檢測依然無法偵測資料符元。因此,我們提出數個用於兩階段雙向中繼網路的相差相位調變架構,而各架構於資料率和錯誤率效能上有不同的取捨。最後,我們以電腦模擬結果驗證各架構的錯誤率效能。
Wireless communications is required to transmit quantity of data more and more. An important studying topic is how to transmit the same quantity of data in a shorter period of time. Recently, two-way relaying is a popular subject, where two terminal nodes transmit to each other with the help of the relay node. Two-phase two-way relaying
(TPTWR) using physical-layer coding is a bandwidth efficient technique. Several TPTWR schemes using differ-ential phase-shift keying (DPSK) which avoid the rate loss due to pilot symbols were proposed.



In this thesis, we first discuss and compare several amplify-and-forward (AF) schemes and decode-and-forward (DF) schemes with single relay. For AF schemes, we indicate the difference of amplify factor in two definitions. For DF schemes, we indicate that if both
terminal nodes use the same signal constellation, except BPSK, the relay is not able to detect data symbols by non-coherent detection. Hence, we propose several DPSK schemes for TPTWR which provide a tradeoff between error performance and data rate. Finally, error performances of the proposed schemes are verified by computer simulations.
