OECC 2007• Japan • July 9-13, 2007 光分碼多工網路中使用延伸漢明碼來消除多重擷取干擾 Optical CDMA Networks Using Extended Hamming Code for Interference Elimination 崑山科技大學 電子工程系 作者 ：楊朝欽、葉蘭英 摘要 本研究將原本使用於錯誤更正的延伸漢明碼作為光分碼多工網路中使用者的序碼，並且利用頻域編碼架構的解碼方式將其他使用者造成的多重擷取干擾消除。將此種序碼加入先前我們實驗室提出的混和分波多工與頻域編碼架構之後，可以發現這個系統的位元錯誤率也獲得改善。 ● 圖三、互補編碼的解碼器。 圖一、互補編碼的編碼器。 圖四、延伸漢明碼作為網路使用者的互補序碼。 圖五、網路主動使用者數與錯誤率關係圖，並先前提出之編碼架構作比較。 圖二、光纖光柵的頻譜。
