Low-Complexity Nonlinearity Compensation for Short-Reach IM/DD Systems using PAM

Not Accessible

Your library or personal account may give you access

Abstract

We investigate the performance of non-regular PAM8 constellations and introduce a novel non-uniformly quantized equalizer to improve nonlinearity compensation in 70 GBd PAM8 back-to-back and 1 km SSMF transmission without additional complexity.
