On the Performance of Multidimensional Constellation Shaping for Linear and Nonlinear Optical Fiber Channel
Bin Chen, Zhiwei Liang, Shen Li +3
Multidimensional constellation shaping of up to 32 dimensions with different spectral efficiencies are compared through AWGN and fiber-optic simulations. The results show that no c…
Integrated Sensing and Communications with MIMO-OTFS
Musa Furkan Keskin, Carina Marcus, Olof Eriksson +3
Orthogonal time frequency space (OTFS) is a promising alternative to orthogonal frequency division multiplexing (OFDM) for high-mobility communications. We propose a novel multiple…
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…
