摘要(中)

區塊衰退通道是無線通訊常見的通道模型，而非同調檢測因不需傳送前導符元做通道估測，所以沒有速率損失的問題。就我們所知，沒有針對區塊衰退通道之非同調區塊碼的相關研究發表，在此篇論文中，我們將研究此主題。我們先使用電腦搜尋無結構的短區塊碼，接著提出用短的區塊碼串成長區塊碼的架構。最後，我們將這些區塊碼串接渦輪碼以進一步改善錯誤效能。電腦模擬結果顯示，與前導符元協助調變相比，我們的碼都具有較好的錯誤率。

摘要(英)

A block fading channel is a common wireless communication channel model. Unlike pilot symbol assisted modulation (PSAM), noncoherent detection does not has the problem of rate loss due to pilot symbols. As far as we know, there are no research results of noncoherent block codes for block fading channels. In this thesis, we focus on this subject. First, short noncoherent block codes without structures are searched by computers. Then, a scheme of long noncoherent block codes composed of short noncoherent block codes is proposed. Finally, the obtained codes are concatenated with a turbo code for further improving the error performance. Simulation results show that, compared with PSAM, our codes have better error performance.
