Blind Equalization and Channel Estimation in Coherent Optical Communications Using Variational Autoencoders
Vincent Lauinger, Fred Buchali, Laurent Schmalen
We investigate the potential of adaptive blind equalizers based on variational inference for carrier recovery in optical communications. These equalizers are based on a low-complex…
