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…
Performance Metrics for Systems with Soft-Decision FEC and Probabilistic Shaping
Tsuyoshi Yoshida, Magnus Karlsson, Erik Agrell
High-throughput optical communication systems utilize binary soft-decision forward error correction (SD-FEC) with bit interleaving over the bit channels. The generalized mutual inf…
Multidimensional Sampling of Isotropically Bandlimited Signals
Erik Agrell, Balázs Csébfalvi
A new lower bound on the average reconstruction error variance of multidimensional sampling and reconstruction is presented. It applies to sampling on arbitrary lattices in arbitra…
