增強型動態解碼轉傳結合網路編碼於雙向中繼站之符元錯誤率分析

我們提出增強型動態解碼轉傳結合網路編碼合作式通訊系統。它為有效提升分集多工權衡與有效降低中斷機率之合作式傳輸通訊協定。本論文將分析單一中繼站情況下，增強型動態解碼轉傳結合網路編碼系統之符元錯誤率。提出其相位偏移調變與正交振幅調變於雷利衰減通道與仲上衰減通道之準確符元錯誤率；並建立漸進近似錯誤率，在高訊號雜訊比下可以有效逼近準確錯誤率。

We propose the enhanced dynamic decode-and-forward cooperative network coding (EDDF-CNC) system, which achieves good diversity-multiplexing gain tradeoff (DMT) and low outage probability. In this thesis, symbol error rate (SER) analysis is provided for a single relay of enhanced dynamic decode-and-forward cooperative network coding protocol in wireless network. Closed-form SER formulas for the cooperation system with PSK and QAM signals over Rayleigh and Nakagami-m fading channels has been derived. Moreover, the asymptotic approximations are established to show, in which one of them is tight at high signal-to-noise ratio (SNR).
