Probabilistic Eigenvalue Shaping for Nonlinear Fourier Transform Transmission
Andreas Buchberger, Alexandre Graell i Amat, Vahid Aref +1
We consider a nonlinear Fourier transform (NFT)-based transmission scheme, where data is embedded into the imaginary part of the nonlinear discrete spectrum. Inspired by probabilis…
Achieving Maximum Distance Separable Private Information Retrieval Capacity With Linear Codes
Siddhartha Kumar, Hsuan-Yin Lin, Eirik Rosnes +1
We propose three private information retrieval (PIR) protocols for distributed storage systems (DSSs) where data is stored using an arbitrary linear code. The first two protocols,…
Nonlinear Interference Mitigation via Deep Neural Networks
Christian Häger, Henry D. Pfister
A neural-network-based approach is presented to efficiently implement digital backpropagation (DBP). For a 32x100 km fiber-optic link, the resulting "learned" DBP significantly red…
Demodulation and Detection Schemes for a Memoryless Optical WDM Channel
Kamran Keykhosravi, Morteza Tavana, Erik Agrell +1
It is well known that matched filtering and sampling (MFS) demodulation together with minimum Euclidean distance (MD) detection constitute the optimal receiver for the additive whi…
Bounds on the Per-Sample Capacity of Zero-Dispersion Simplified Fiber-Optical Channel Models
Kamran Keykhosravi, Giuseppe Durisi, Erik Agrell
A number of simplified models, based on perturbation theory, have been proposed for the fiber-optical channel and have been extensively used in the literature. Although these model…
