( c ) propose the scheme to implementing the coder and deoder of optical time - spreading / frequency - hopping, by assigning two orthogonal codes for one user and using these two codes to encoding 1 and 0 respectively, differential detection can be adopted. not only improves system performances in ber, but also resists the interference such as mai, and does n ' t need any control devices to evaluate the optimum decisive threshold
通過給每個用戶指定互相關為0的兩個地址碼分別發送1和0信號以及在接收端採用差分檢測技術,避免了ook (開關鍵控)光通信系統中0不發送光脈沖和ook常規檢測方式下最佳判決門限必須根椐用戶數等外界環境而改變,從而提高了系統性能和降低了系統的復雜度。 -
