About the session

Tutorial - Tu.C.1.T Constellation Optimization for Fiber-optic Channels

Metodi Plamenov Yankov

Technical University of Denmark

The problem of constellation optimization, also known as shaping, is discussed in the context of optical fiber communication channels affected by linear and non-linear noise. First, the information-theoretic principles of constellation shaping are described. Then, popular geometric and probabilistic shaping strategies are presented, analyzed and compared, with a focus on the autoencoder method. The tradeoffs between accuracy, speed and practicality of different channel models used for optimization are summarized. The problem of transmitting binary data which are uniformly distributed is introduced. Pragmatic coded modulation systems employing constellation shaping are briefly described.

Speaker Biography Metodi Plamenov Yankov (Senior Member, IEEE, member, OPTICA) received his B.Eng. degree in radio communications from the Technical University of Sofia, Bulgaria, in 2010, his M.Sc. degree in signals and transmission technology for telecommunications from the Technical University of Denmark (DTU), in 2012, and his Ph.D. degree in constellation constrained capacity estimation and near-capacity achieving digital methods from DTU in 2016. He is currently serving as an associate professor at DTU Electro, the Coding and Visual Communications Group. He is the author of nearly 100 scientific papers, primarily in the area of signal processing and optimization of optical transmission systems. His research interests include among others information and communication theory of digital transceivers, digital signal processing techniques in general and for wireless and optical fiber communications in particular, machine learning, forward error correction codes, and information theory of biometrics.
