Impact of 4D channel distribution on the achievable rates in coherent optical communication experiments
Tobias A. Eriksson, Tobias Fehenberger, Peter A. Andrekson +3
We experimentally investigate mutual information and generalized mutual information for coherent optical transmission systems. The impact of the assumed channel distribution on the…
Rates Achievable on a Fiber-Optical Split-Step Fourier Channel
Kamran Keykhosravi, Erik Agrell, Giuseppe Durisi
A lower bound on the capacity of the split-step Fourier channel is derived. The channel under study is a concatenation of smaller segments, within which three operations are perfor…
Stochastic Digital Backpropagation with Residual Memory Compensation
Naga V. Irukulapati, Domenico Marsella, Pontus Johannisson +3
Stochastic digital backpropagation (SDBP) is an extension of digital backpropagation (DBP) and is based on the maximum a posteriori principle. SDBP takes into account noise from th…
Replacing the Soft FEC Limit Paradigm in the Design of Optical Communication Systems
Alex Alvarado, Erik Agrell, Domanic Lavery +2
The FEC limit paradigm is the prevalent practice for designing optical communication systems to attain a certain bit-error rate (BER) without forward error correction (FEC). This p…
Influence of Behavioral Models on Multiuser Channel Capacity
Erik Agrell, Magnus Karlsson
In order to characterize the channel capacity of a wavelength channel in a wavelength-division multiplexed (WDM) system, statistical models are needed for the transmitted signals o…
