End-to-End Learning of Geometrical Shaping Maximizing Generalized Mutual Information
Kadir Gümüs, Alex Alvarado, Bin Chen +2
GMI-based end-to-end learning is shown to be highly nonconvex. We apply gradient descent initialized with Gray-labeled APSK constellations directly to the constellation coordinates…
Performance Monitoring for Live Systems with Soft FEC and Multilevel Modulation
Tsuyoshi Yoshida, Mikael Mazur, Jochen Schröder +2
Performance monitoring is an essential function for margin measurements in live systems. Historically, system budgets have been described by the Q-factor converted from the bit err…
Post-FEC BER Benchmarking for Bit-Interleaved Coded Modulation with Probabilistic Shaping
Tsuyoshi Yoshida, Alex Alvarado, Magnus Karlsson +1
Accurate performance benchmarking after forward error correction (FEC) decoding is essential for system design in optical fiber communications. Generalized mutual information (GMI)…
An Improved Model of Nonlinear Fiber Propagation in the Presence of Kerr Nonlinearity and Stimulated Raman Scattering
Hami Rabbani, Gabriele Liga, Vinicius Oliari +4
Ultra-wideband fiber optical transmission suffers from both Kerr nonlinearity and stimulated Raman scattering (SRS). Mathematical models that address the interplay between Kerr non…
Preferred Design of Hierarchical Distribution Matching
Tsuyoshi Yoshida, Magnus Karlsson, Erik Agrell
Distribution matching and dematching (DM/invDM) are key functions in probabilistic shaping (PS). Recently techniques for low complexity implementation of DM/invDM have been well st…
