基于SSFBG的OCDMA编解码仿真

OCDMA encoder-decoder simulation based on SSFBG

采用分步傅里叶法求解非线性薛定谔方程,数值分析了基于超结构光纤布拉格光栅(SSF-BG)技术的光码分多址(OCDMA)时域编解码系统性能.指出在基于SSFBG的OCDMA编解码系统中,系统的误码率(BER)随着码长增加而加大,双极性码的性能优于单极性码.

The performance of OCDMA encoder-decoder system in the time domain based on SSFBG was simulated by the split-step Fourier method（SSFM）that can solve the coupled nonlinear Schrdinger equation（CNLSE）.It is point out that the longer code length is,the large BER is.And the performance of bipolar code is better than that of unipolar code.
