Mitigation of EEPN in Coherent Optical Systems With Low-Speed Digital Coherence Enhancement

A method for mitigating local oscillator (LO) phase noise-induced impairment, also known as equalization-enhanced phase noise, in coherent optical systems is discussed. The method is suitable for real-time implementation and requires hardware with a bandwidth much lower than the signal baud rate, ev...
