Geometric Constellation Shaping for Fiber-Optic Channels via End-to-End Learning
Ognjen Jovanovic, Francesco Da Ros, Darko Zibar +1
End-to-end learning has become a popular method to optimize a constellation shape of a communication system. When the channel model is differentiable, end-to-end learning can be ap…
Capacity and Achievable Rates of Fading Few-mode MIMO IM/DD Optical Fiber Channels
Metodi P. Yankov, Francesco Da Ros, Søren Forchhammer +1
The optical fiber multiple-input multiple-output (MIMO) channel with intensity modulation and direct detection (IM/DD) per spatial path is treated. The spatial dimensions represent…
Probabilistically Shaped 4-PAM for Short-Reach IM/DD Links with a Peak Power Constraint
Thomas Wiegart, Francesco Da Ros, Metodi Plamenov Yankov +3
Probabilistic shaping for intensity modulation and direct detection (IM/DD) links is discussed and a peak power constraint determined by the limited modulation extinction ratio (ER…
Experimental Verification of Rate Flexibility and Probabilistic Shaping by 4D Signaling
Fabian Steiner, Francesco Da Ros, Metodi Plamenov Yankov +4
The rate flexibility and probabilistic shaping gain of -dimensional signaling is experimentally tested for short-reach, unrepeated transmission. A rate granularity of 0.5 bits/Q…
Experimental Demonstration of Dual Polarization Nonlinear Frequency Division Multiplexed Optical Transmission System
Simone Gaiarin, Auro Michele Perego, Edson Porto da Silva +2
Multi-eigenvalues transmission with information encoded simultaneously in both orthogonal polarizations is experimentally demonstrated. Performance below the HD-FEC limit is demons…
Experimental Comparison of Probabilistic Shaping Methods for Unrepeated Fiber Transmission
Julian Renner, Tobias Fehenberger, Metodi P. Yankov +4
This paper studies the impact of probabilistic shaping on effective signal-to-noise ratios (SNRs) and achievable information rates (AIRs) in a back-to-back configuration and in unr…
