Performance Prediction Recipes for Optical Links
Erik Agrell, Marco Secondini, Alex Alvarado +1
Although forward error-correction (FEC) coding is an essential part of modern fiber-optic communication systems, it is impractical to implement and evaluate FEC in transmission exp…
Compressed Shaping: Concept and FPGA Demonstration
Tsuyoshi Yoshida, Koji Igarashi, Magnus Karlsson +1
Probabilistic shaping (PS) has been widely studied and applied to optical fiber communications. The encoder of PS expends the number of bit slots and controls the probability distr…
On the Performance under Hard and Soft Bitwise Mismatched-Decoding
Tsuyoshi Yoshida, Mikael Mazur, Jochen Schröder +2
We investigated a suitable auxiliary channel setting and the gap between Q-factors with hard and soft demapping. The system margin definition should be reconsidered for systems emp…
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)…
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…
Hierarchical Distribution Matching for Probabilistically Shaped Coded Modulation
Tsuyoshi Yoshida, Magnus Karlsson, Erik Agrell
The implementation difficulties of combining distribution matching (DM) and dematching (invDM) for probabilistic shaping (PS) with soft-decision forward error correction (FEC) codi…
Performance Metrics for Systems with Soft-Decision FEC and Probabilistic Shaping
Tsuyoshi Yoshida, Magnus Karlsson, Erik Agrell
High-throughput optical communication systems utilize binary soft-decision forward error correction (SD-FEC) with bit interleaving over the bit channels. The generalized mutual inf…
