Abstract :
The statistics and impact of equalization-enhanced phase noise (EEPN) is investigated for systems with electronic chromatic dispersion compensation using DSP. EEPN impairment induces larger phase noise than amplitude noise. Optimal linear equalizer in the presence of EEPN is derived but negligible performance improvement is obtained, indicating that EEPN is not easy to mitigate using simple DSP techniques.
