| dc.description.abstract | "單載波分頻多工(SC-FDM)是當代無線通訊上行傳輸廣泛使用的技術。為了改善符元決策的性能表現，有著決策回饋的疊代等化演算法是需要被考慮的。在本篇論文中提出一種適用於單載波分頻多工系統的疊代決策回饋混合式等化演算法(IDFHE)，此演算法結合了修正式線性最小均方誤差(MLM)和約束最小平方(CLS)兩種非疊代等化演算法。不同於以往的決策回饋等化技術，本文所提出的IDFHE演算法在疊代過程中根據不同等化器的特性使用了不同的等化器設計準則，藉此改善符元決策性能。在性能表現的部分，本文討論了在隨機分段頻散通道上的位元錯誤機率(bit error probability, BEP)以及計算複雜度，結果顯示本文提出的演算法相比以往的決策回饋等化(DFE)演算法可以達到更好的位元錯誤機率並且維持相似的計算複雜度。此外，經由分析訊號對干擾加雜訊比(signal-to-interference-plus-noise ratio, SINR)、訊號雜訊比(signal-to-noise power ratio, SNR)推導出的位元錯誤機率也被展示為IDFHE性能結果的精確分析和分析下界。隨著Rician K值增加，模擬結果愈來愈接近分析下界，代表干擾消除的效果隨著K值增加而愈來愈好。" | zh_TW |
