Log-CCDM: Distribution Matching via Multiplication-free Arithmetic Coding
Yunus Can Gültekin, Frans M. J. Willems, Alex Alvarado
Recent years have seen renewed attention to arithmetic coding (AC). This is thanks to the use of AC for distribution matching (DM) to control the channel input distribution in prob…
Kurtosis-limited Sphere Shaping for Nonlinear Interference Noise Reduction in Optical Channels
Yunus Can Gültekin, Alex Alvarado, Olga Vassilieva +4
Nonlinear interference (NLI) generated during the propagation of an optical waveform through the fiber depends on the fourth order standardized moment of the channel input distribu…
Temporal Energy Analysis of Symbol Sequences for Fiber Nonlinear Interference Modelling via Energy Dispersion Index
Kaiquan Wu, Gabriele Liga, Alireza Sheikh +2
The stationary statistical properties of independent, identically distributed (i.i.d.) input symbols provide insights on the induced nonlinear interference (NLI) during fiber trans…
Achievable Information Rates for Probabilistic Amplitude Shaping: An Alternative Approach via Random Sign-Coding Arguments
Yunus Can Gültekin, Alex Alvarado, Frans M. J. Willems
Probabilistic amplitude shaping (PAS) is a coded modulation strategy in which constellation shaping and channel coding are combined. PAS has attracted considerable attention in bot…
Probabilistic Shaping for Finite Blocklengths: Distribution Matching and Sphere Shaping
Yunus Can Gültekin, Tobias Fehenberger, Alex Alvarado +1
In this paper, we provide for the first time a systematic comparison of distribution matching (DM) and sphere shaping (SpSh) algorithms for short blocklength probabilistic amplitud…
First Experimental Demonstration of Probabilistic Enumerative Sphere Shaping in Optical Fiber Communications
Sebastiaan Goossens, Sjoerd van der Heide, Menno van den Hout +8
We transmit probabilistic enumerative sphere shaped dual-polarization 64-QAM at 350Gbit/s/channel over 1610km SSMF using a short blocklength of 200. A reach increase of 15% over co…
