摘要

基于对LSOOC码的修正

提出了一种光谱幅度编码光码分多址（SAC-OCDMA）地址码的设计方案。分析了码字特性

与Hardmard、MQC、MFH、BIBD（m=2）码做了比较

设计了可调谐光纤布拉格光栅（FBG）编解码器

阐述了编解码原理。分析结果表明

该码字容量大

编解码方法简单

在光源和信道理想条件下可以消除多址干扰。

Abstract

On the basis of the modification of LSOOC

a new design plan for the address code for the spectral-amplitude-coding optical CDMA（SAC-OCDMA） system is proposed.The characteristics of the code words are analyzed

its comparisons with Hardmard

MQC

MFH

BIBD（m=2） made

tunable Fiber Bragg Grating（FBG） codec designed and the principle of coding and decoding explained.The analytical results reveal that the new code word is large in capacity

simple in coding and decoding and immune from Multi-Address Interference（MAI） when the optical source and channel are ideal.
