摘要
简要介绍了光码分多址网络的基本结构和误码性能 ,分析了光纤传输导致的光脉冲展宽对系统误码率的影响 ,提出了计算误码率的修正公式 ,并以数值求解非线性薛定谔方程为主要分析方法 ,对误码性能进行了数值仿真 。
The fundamental principles of optical code division multiple access (OCDMA) networks are introduced firstly.Then,BER equation is upgraded according to the widening of optical plus after transmission.Finally,a program is made to simulated OCDMA networks and upgraded BER equation is verified.
