摘要

本文提出了一种基于低成本宽带光源如发光二极管(LED)的幅度谱编码的光码分多址(OCDMA) CDMA系统中的零互相关码(ZCC)。我们还研究了如何将LED的切片光谱用作ZCC代码中具有成本效益的光源。我们的系统只需要标准的光学元件和简单的直接检测接收器。我们表明，当权重数= 4时，最多可以有100个用户进行异步传输，平均误码率为10−9。该ZCC代码还表明，在最小接收功率为- 25.5 dBm的情况下，可以实现10−9的误码率。

LED spectrum slicing for ZCC SAC-OCDMA coding system

In this paper we propose a Zero Cross-correlation (ZCC) code in Optical Code Division Multiple Access (OCDMA) CDMA system based on amplitude spectral encoding of low-cost broadband sources such as Light Emitting Diode (LED). We also study how the sliced spectrum of LED can be used as a cost-effective light source in ZCC code. Our system requires only standard optical elements and simple direct-detection receivers. We show that for number of weight = 4, up to 100 users can transmit asynchronously with an average bit error rate equal to 10−9. This ZCC code also demonstrates that BER of 10−9 can be achieved within the minimum received power of −25.5 dBm.
