Data-driven Enhancement of the Time-domain First-order Regular Perturbation Model
Astrid Barreiro, Gabriele Liga, Alex Alvarado
A normalized batch gradient descent optimizer is proposed to improve the first-order regular perturbation coefficients of the Manakov equation, often referred to as kernels. The op…
Geometrically-Shaped Multi-Dimensional Modulation Formats in Coherent Optical Transmission Systems
Bin Chen, Yi Lei, Gabriele Liga +4
Shaping modulation formats in multi-dimensional (MD) space is an effective approach to harvest spectral efficiency gains in both the additive white Gaussian noise (AWGN) channel an…
Band-ESS: Streaming Enumerative Coding with Applications to Probabilistic Shaping
Yunus Can Gültekin, Frans M. J. Willems, Alex Alvarado
Probabilistic amplitude shaping (PAS) is on track to become the de facto coded modulation standard for communication systems aiming to operate close to channel capacity at high tra…
Analytical SNR Prediction in Long-Haul Optical Transmission using General Dual-Polarization 4D Formats
Zhiwei Liang, Bin Chen, Yi Lei +2
Nonlinear interference models for dual-polarization 4D (DP-4D) modulation have only been used so far to predict signal-signal nonlinear interference. We show that including the sig…
Temporal Properties of Enumerative Shaping: Autocorrelation and Energy Dispersion Index
Yunus Can Gültekin, Kaiquan Wu, Alex Alvarado
We study the effective SNR behavior of various enumerative amplitude shaping algorithms. We show that their relative behavior can be explained via the temporal autocorrelation func…
On Optimum Enumerative Sphere Shaping Blocklength at Different Symbol Rates for the Nonlinear Fiber Channel
Yunus Can Gültekin, Olga Vassilieva, Inwoong Kim +3
We show that a 0.9 dB SNR improvement can be obtained via short-blocklength enumerative sphere shaping for single-span transmission at 56 GBd. This gain vanishes for higher symbol…
