초록

본 논문은 symmetric balance incomplete block design(BIBD) code와 arrayed-waveguide grating(AWG) router의 주기적인 특성을 이용하여 optical CDMA network을 위한 coder-decoder(codec)을 구성하였다. 기존의 M-sequence code를 이용한 경우보다 다양한 구성을 할 수 있고 이 시스템의 잡음인 phase-induced intensity noise(PIIN)와 thermal noise를 분석하여 BER을 계산한 결과 향상된 성능을 보임을 알 수 있었다.

By using the cyclic properties of symmetric balance incomplete block design(BIBD) codes and arrayed-waveguide grating(AWG) routers, a compact optical CDMA network coder-decoder(codec) can be constructed. It can be observed that the various code families obtained by BIBD improve the BER performance compared to M-sequence code.
