实现光码分多址系统的关键技术

Main Techniques in the Implementation of Optical Code Division Multiple Access System

从９０年代开始，国外对光码分多址（ＯＣＤＭＡ）的研究和应用的兴趣日益高涨，而在国内目前还未见有此方面实质性进展的报道。文中在介绍ＯＣＤＭＡ系统及其特点的基础上，分析ＯＣＤＭＡ系统实现中的关键技术，包括：扩频序列研究、信道干扰的消除以及光编码器／解码器的实现等。

There has been an increasing interest in the research of Optical Code Division Multiple Access (OCDMA) since the mid. 90s. This paper presents a review of OCDMA system and its distinguishing features, analyses main techniques in the implementation of OCDMA system, and discusses several problems we now have to solve.
