在非同相光纖分碼多工系統中，傳統上大部分是使用著能量準位檢測之硬式限幅接收器作為分析。然而由於環境溫度的變化與碼移動技術，使用能量準位檢測之準度及其性能均會受影響。因此，我們提出一個新的使用功率準位檢測的解碼方法，並且證明其比能量準位檢測有更好的性能表現。在本篇論文中，我們使用了OptiSystemTM來對能量準位檢測和功率準位檢測之光纖分碼多工系統作設計模擬與驗證。最後，我們利用數值分析和電腦模擬驗證在全光硬體中之功率準位檢測接收器之設計。

Pulse-energy detection with hard-limiting receivers has traditionally been used in incoherent optical code-division multiple access (O-CDMA) systems in most of analyses. However, the variations of environmental temperature and code-shifting technique effects the pulse-energy detection and performance. Therefore, a new decoding method using pulse-power detection has recently been proposed and proved to give better performance than the pulse-energy detection. In this thesis, the O-CDMA system with pulse-power and pulse-energy detection is designed and validated with OptiSystemTM –an optical hardware simulator. Finally, numerical results and computer simulation results are presented to validate the application of pulse-power detection in optical hardware.
