| 摘 要： | 分析了一种非循环单重合码的色散效应,并将色散效应等效为功率衰减因子,得出同时考虑差拍噪声和色散后FFH-OCDMA系统的误码率性能.结果表明,非循环单重合码的色散效应虽然比循环单重合码有所增加,但它大大降低了互相关干扰,也大大降低了差拍噪声,从而提高了系统的误码率性能.

| Abstract: | The impact of chromatic dispersion of non-cyclic one-coincidence sequence is analyzed, and it is equivalent to an energy attenuation factor. Then, the BER performance of FFH-OCDMA is educed after considering the effect of optical beat interference and chromatic dispersion. Analysis results show that the BER performance of non-cyclic one-coincidence sequence is better than cyclic one-coincidence sequence |
