Investigation on the Impact of Additional Connections to Feedforward Neural Networks for Equalization in PAM4 Short-Reach Direct Detection Links

Not Accessible

Your library or personal account may give you access

Abstract

Different additional connections onto feedforward neural networks are investigated for equalization in a 50-Gb/s PAM4 short-reach direct detection link. The auto-regressive and cascade structures demonstrate the most significant performance improvement with limited additional computational complexity.
