摘要
光纤信道的色散和非线性效应会导致单极性光CDMA系统性能下降,由此提出采用非零色散位移光纤(NZ-DSF)搭配色散补偿光纤(DCF)来改善系统性能的方法。数值结果表明:该方法能有效降低色散和非线性效应导致的多用户干扰,改善系统性能。
The dispersion and non- linear effect can deteriorate the optical CDMA system performance . A scheme of using none zero dispersion shift fibre(NZ- DSF) and dispersion compensate fibre(DCF) to enhance the performance of system is proposed. Numerical result shows that the proposed scheme can enhance the performance of system effictivly
