摘要

基于单硬限幅器（OHL）的同步光码分多址（OCDMA）系统不能完全消除信道串扰

引入了双OHL结构来优化系统传输性能。文章给出地址码的码重、光谱强度、用户数与误码率及同异步系统归一化吞吐量间的关系

结果表明:在用户数与地址码重相差较大的情况下

双OHL同步OCDMA系统误码率下降明显且比异步系统的归一化吞吐量大。

Abstract

As single Optical Hard Limiter（OHL）-based synchronous OCDMA system cannot be entirely immune from channel crosstalk

double OHL structure is introduced to optimize the system transmission performance.This paper presents the relationship between the code weight of address code

spectrum intensity

number of users and the bit error probability and that between the normalized throughputs of the synchronous and asynchronous systems.The results show that when the number of users is quite different from the address code weight

the bit error probability of the double OHL-based synchronous OCDMA system remarkably drops and produces higher normalized throughput than the asynchronous system.
