Sebastian Stern

Dr.-Ing. Sebastian Stern serves as a Senior Researcher at the Institute of Communications Engineering, Ulm University, Germany. His research focuses on advanced communication systems with particular expertise in MIMO transmission, lattice-based coding, and optical communications. Stern maintains active collaborations with researchers including Robert F.H. Fischer and Johannes K. Fischer across multiple publications.

His educational background includes a dissertation titled Advanced Equalization and Coded-Modulation Strategies for Multiple-Input/Multiple-Output Systems (2019) from Ulm University, building upon his Master's thesis Comparison of the peak value behavior of single- and multi-carrier methods (2012) which earned the VDE Award for Outstanding Master Thesis.

Stern's research interests span wireless communications, optical transmission systems, and advanced signal processing techniques. His work demonstrates significant contributions to 4D constellation design using Hurwitz and Eisenstein integers, lattice reduction methods for MIMO systems, and non-binary coding schemes for high-throughput fiber-optic communication. Recent publications show expanding work into quaternionic lattices and AI applications for network security.

His publication record shows consistent output since 2013 with 25+ journal and conference papers, including high-impact publications in IEEE Transactions on Information Theory and Journal of Lightwave Technology. Recent work (2023-2025) demonstrates continued innovation in integer-forcing techniques, quaternionic Minkowski reduction, and 4D constellation optimization.

• VDE Award for Outstanding Master Thesis (2013)

Stern has taught multiple courses at Ulm University including Communications Engineering lab courses, Multiuser Communications and MIMO Systems exercises, and Signale und Systeme tutorials between 2013-2017. His teaching experience complements his research in practical implementation of advanced communication techniques.
