Digital Predistortion Enhancement by Convolutional Neural Network for Probabilistic Shaped Discrete Multi-Tone Signal Transmission in Passive Optical Network

Not Accessible

Your library or personal account may give you access

Abstract

We experimentally demonstrate a 68.2-Gb/s net data-rate probabilistic shaped discrete multi-tone transmission in passive optical network with 11G-class devices. The convolutional- neural-network strengthens digital predistortion performance with 1.1-dB improvement of system sensitivity over linear pre-equalization.
