Abstract

A new code structure for spectral-amplitude-coding optical CDMA based upon reconstructed modified double weight codes is proposed. The newly proposed code possesses ideal cross-correlation properties. By using fiber Bragg grating(FBG) in front of optical decoder, we can get the improved performance of the proposed system with the consideration of phase-induced intensity noise(PIIN).

변형된 modified double weight code를 사용하여 효율적인 spectral-amplitude-coding optical CDMA를 구현하였다. 수신단의 optical decoder 앞에 fiber Bragg grating(FBG)을 사용하여 이 시스템의 주된 잡음인 phase-induced intensity noise(PIIN)를 대폭 줄여 향상된 시스템의 특성을 보일 수 있었다.
