鑑定OFDM系統中非線性通道之研究

為了解決DAB Band的問題，作者鄭人禾 這樣論述：

本論文提出兩種簡單準確的通用公式，主要是用來鑑定正交分頻多工系統中的非線性通道。正交分頻多工系統是一種被廣泛採用的寬頻通訊應用技術。正交分頻多工系統訊號很容易受到通訊網路中非線性通道的影響。使得正確估計OFDM 系統非線性通道的任務變得很重要。非線性通道通常是由VolterraSeries 來表示，非線性通道鑑定的任務就是確定Volterra Kernel。當非線性系統階數增加時，這項任務會變得非常困難。本論文，論述OFDM 信號的高階統計特性和多層分解特性，以克服遇到的瓶頸並推導出解決Volterra Kernel 鑑定的通用方法。這兩種方法各有優缺點。OFDM 信號的高階統計特性法是利用

高階自動矩為頻域Volterra Kernel 提出閉式表達式。使用高階統計特性這個方法可以推導出上至5 階非線性通道之簡單公式。多層分解的方法是透過設計具有時域或頻域頻譜凹陷的不同輸入信號來激發非線性系統，這種方法理論上可適用於任意階之非線性通道，且不限於OFDM 系統，但會產生較大的計算複雜度。基於這兩種方法，本論文推導準確簡單的方法來鑑定高階非線性正交分頻多工系統系統Volterra Kernel 的通用公式。理論分析和模擬結果顯示，所得到的解決方法都達到了最小均方誤差。
