Research on bipolar optical code-division multiple access system
摘要
对光码分多址 (OCDMA)系统中的地址码
包括单极性码和双极性码的容量和性能进行了分析比较
给出了 4种双极性编码方案 .单极性系统无论是在确定误码率条件和同时传输用户数方面
还是在系统总用户数方面
都远不及双极性系统
双极性系统是 OCDMA系统实现大容量的有效途径之一 .
Abstract
The paper analyses the performance of the address codes for optical code division multiple access (OCDMA) system
including unipolar and bipolar codes. Four kinds of bipolar encoding schemes are presented. The unipolar system is much inferior to the bipolar system in many fields and the later is a practical way to implement OCDMA system with large capacity.
