摘要

提出了一种新的、实现光ＣＤＭＡ的方案。它采用平衡发射和接收技术同时使用Ｍａｃｈ－Ｚｅｈｎｄｅｒ干涉链来进行地址编码。该ＣＤＭＡ系统接近波分复用的性能，但是也面临一些有待解决的问题，例如多用户时的谱干扰，散弹噪声等。而本系统可以在非相干调制光系统中得到地址码的真正正交，从而改善系统的性能。

Abstract

In this paper

We present the scheme of a bipolar spectrally encoded optical code division multiple access system

using balanced transmission and Mach-Zehnder encoder chains. The optical CDMA system closely approach WDM performance. The main issues were speckle from multiple users

shot noise

and true code orthogonality within a non-coherent system.
