Fiber Nonlinearity Mitigation by Short-Length Probabilistic Constellation Shaping for Pilot-Aided Signaling

no code implementations • 14 Dec 2020 • Tobias Fehenberger, Helmut Griesser, Jörg-Peter Elbers

The reason for this behavior is that short-length PCS implicitly induces some temporal properties in the shaped transmit sequence that are beneficial for the fiber-optic channel.

On the Impact of Finite-Length Probabilistic Shaping on Fiber Nonlinear Interference

no code implementations • 12 Jun 2020 • Tobias Fehenberger

The interplay of shaped signaling and fiber nonlinearities is reviewed in the asymptotic and finite-length regime.

In this paper, we study amplitude shaping schemes for the probabilistic amplitude shaping (PAS) framework as well as algorithms for constant-composition distribution matching (CCDM).

This temporal property results in weaker nonlinear interactions, and thus higher SNR, for short CC sequences.
