| 摘 要： | 对相干光单载波频域均衡系统(CO-SCFDE)、相干光单载波频分复用系统(CO-SCFDM)以及相干光正交频分复用系统(CO-OFDM)的理论和实验进行了对比研究,结果表明基于频域均衡的相干光单载波系统既保留了正交频分复用方式计算复杂度较低、频谱效率高和抗色散性能好的优点,又有效地减小了光纤非线性带来的传输损伤,是高速长距离光纤传输的一种有潜力的技术方案。

| Abstract: | We compare the coherent optical single carrier frequency domain equalization(CO-SCFDE) system and the coherent optical single carrier frequency division multiplexing(CO-SCFDM) system with coherent optical orthogonal frequency division multiplexing(CO-OFDM) system by simulation and experiment.The results show that the single carrier systems based on frequency domain equalization not only inherit the advantages of OFDM system,but also reduce nonlinear transmission impairment.They are very promising for future long-haul optical transmission. |
