IET Optoelectronics, Volume 18, Issue 5, Page 131-139, October 2024.1. The data‐free guided coherent reception DSP algorithm proposed based on spectral clustering can effectively suppress a variety of physical damage and increase the system’s OSNR tolerance. 2. When the bit error rate is 1.9E‐2, the spectral clustering‐based data‐agnostic DSP solution extends the maximum transmission distance of a 14GBaud PM‐16QAM ...
