供混合光纖同軸傳輸系統使用之多路徑模擬器及64-QAM基頻處理電路製作

Abstract

在本論文中,我們製作供混合光纖同軸傳輸系統使用之多路徑模 擬器,包括數位的衰減,數位的能量合成器 ,並利用最佳化的方法找出模擬 器的參數.另外也製作64-QAM基頻處理電路,包括攪碼器(Scrambler), Reed-Solomon 碼,Convolutional Interleaving及Reed-Solomon 碼的相 關電路包括:頻率合成器(frequency synthesizer),(de-)Multi-plexer, 資料的壓縮,資料的萃取,frame synchronization等. In the thesis we implement the multipath simulator for HFC systems ,including digital attenuator , digital power combiner , and find the para-meters by means of optimization. We also implement 64-QAM baseband processingcircuits including scrambler , Reed-Solomon code , Convolutional Interleaving, and the related circuits of Reed-Solomon Code including frequency synthesizer, (de-)Multiplexer,data compression , data retraction , frame synchronization... etc
