与微分双相编码给调音的振幅移动(D8PSK/ASK ) 调音的微分 8 水平阶段移动(DBC ) 的一种新奇直角的调整格式的原则被介绍。基于它,一个光标记计划,收费载重在是 100 Gbit/s D8PSK 信号和标签是 10 Gbit/s DBC 问信号,被建议并且模仿。结果与另外的当前的计划相比,并且传播的效果变化调整扑灭比率(嗯) 并且系统性能上的收到的功率分别地被分析。光谱效率和小点错误评估的结果表演(BER ) 极大地被改进,并且什么时候调整嗯被增加到 11 dB,在收费载重和标签之间的平衡表演被完成。
The principle of a novel orthogonal modulation format of differential 8-1evel phase-shift keying amplitude-shift keying (D8PSK/ASK) with differential bi-phase encoding (DBC) is introduced. Based on it, an optical labeling scheme, in which the payload is 100 Gbit/s D8PSK signal and the label is 10 Gbit/s DBC-ASK signal, is proposed and simulated. The results arc compared with other current schemes, and the effects of transmission range, modulation extinction ratio (ER) and received power on system performance are analyzed, respectively. The results show that the spectrum efficiency and bit error rate (BER) are improved greatly, and when the modulation ER is increased to 11 dB, the balanced performance between the payload and label is achieved.
