摘要

针对波分复用-无源光网络（WDM-PON）的系统可容纳用户量问题，为扩大系统的容量和速率，同时保证光纤的带宽需求，文章提出了一种基于混沌扩频的光码分多址波分复用无源光网络（OCDMA-WDM-PON）系统方案，分析了Henon混沌序列作为地址码的初值敏感性、自相关和互相关等特性，并通过Matlab仿真平台分析了Henon混沌序列与Logistic混沌序列、光正交码（OOC）关于系统误码率（BER）性能的对比，验证了混沌序列在通信系统中作为地址码的可行性和优越性。实验结果表明，混沌序列作为地址码具有性能良好、用户数量大、不易被复制且容易产生地址码的优势。

Abstract

Aiming at the problem of capacity in Wavelength Division Multiplexing-Passive Optical Network (WDM-PON)

Optical Code Division Multiple Access WDM-PON (OCDMA-WDM-PON) based on chaotic spread spectrum is proposed to expand the capacity and rate

ensuring the bandwidth requirement of optical fiber. The initial value sensitivity

auto-correlation and cross-correlation of Henon chaotic sequence as an address code are analyzed. The comparison of Bit Error Ratio (BER) performance between Henon chaotic sequence and Logistic chaotic sequence and Optical Orthogonal Code (OOC) are analyzed by simulation

which verifies the feasibility and superiority of chaotic sequence as address code in communication system. The experimental results show that the chaotic sequence as an address code has the advantages of good performance

large number of users

difficult to copy and easy to generate address code.
