新型调制格式
1.
In short, advanced PMD compensation technology, and PMD mitigation technology such as new modulation format, FEC and PTC are combined dynamically, offering improved solutions for adaptive PMD compensation in high-speed long haul WDM systems, and providing useful reference for theoretical studies and practical applications .
根据多信道的最差信道补偿方案,将粒子群优化(PSO)算法用于多信道的PMD补偿,只采用一个补偿器,在补偿最坏信道的同时保障其它信道的性能;将新型调制格式(DPSK、DQPSK)引入WDM系统多信道PMD补偿系统,与传统OOK调制格式相比取得了很好的PMD缓解效果;将FEC技术中的RS纠错码应用于多信道PMD补偿系统并取得了很好的性能;提出一个基于偏时编码(PTC)技术与Turbo纠错码的PMD补偿新方案,取得了很好的PMD的缓解性能和对系统误码率的改善性能。
