摘要

提出了一种基于频谱聚类的相干光接收机数字信号处理（DSP）方案，该方案利用频谱聚类对 DSP 输出的信号进行聚类。与采用 PM-mQAM 的相干光接收器在超过 100Gbps 速率下运行的现有盲 DSP 算法相比，所提出的方案能有效抑制各种物理损伤，在相同传输距离下实现更低的误码率（BER），从而在相同的前向纠错阈值下实现更长的传输距离。此外，拟议方案在 14GBaud PM-16QAM 相干光传输系统上的仿真表明，在误码率为 1.9E-2 时，最大传输距离从 1700 公里增加到 2000 公里；在误码率为 3.8E-3 时，最大传输距离从 700 公里增加到 900 公里。

An unsupervised coherent receiver digital signal processing algorithm based on spectral clustering with no data preamble

A coherent optical receiver digital signal processing (DSP) scheme is proposed based on spectral clustering, which utilises spectral clustering to cluster the signals outputted by the DSP. Compared to existing blind DSP algorithms for coherent optical receivers operating at over 100Gbps with PM-mQAM, the proposed scheme effectively suppresses various physical impairments, achieving lower bit error rates (BERs) at the same transmission distance, thus enabling longer transmission distances under the same forward error correction threshold. Furthermore, simulations of the proposed scheme on a 14GBaud PM-16QAM coherent optical transmission system show that, at a BER of 1.9E-2, the maximum transmission distance increases from 1700 to 2000 km, and at a BER of 3.8E-3, it increases from 700 to 900 km.
