摘要
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 Schrdinger 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.
