Impairment Identification for PAM-4 Transceivers and Links Using Machine Learning

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate simultaneous TDECQ estimation and impairment identification using convolutional neural networks. Robust training with representative impairments yielded identification accuracy of 100% for TDECQ >2.6 dB, when considering limited bandwidth, signal compression and SNR degradation.
