Communication system's performance is sensitive to bandwidth, power, cost etc. There have
been various solutions to improve the performance, out of them, one of the fundamental …

Abstract Machine learning (ML) and neuromorphic computing have been enforcing problem-
solving in many applications. Such approaches found fertile ground in optical …

We review probabilistic constellation shaping (PCS), which has been a key enabler for
several recent record-setting optical fiber communications experiments. PCS provides both …

A new coded modulation scheme is proposed. At the transmitter, the concatenation of a
distribution matcher and a systematic binary encoder performs probabilistic signal shaping …

Distribution matching transforms independent and Bernoulli (1/2) distributed input bits into a
sequence of output symbols with a desired distribution. Fixed-to-fixed length, invertible, and …

Different aspects of probabilistic shaping for a multispan optical communication system are
studied. First, a numerical analysis of the additive white Gaussian noise (AWGN) channel …

We describe a method to estimate the capacity limit of fiber-optic communication systems
(or¿ fiber channels¿) based on information theory. This paper is divided into two parts. Part 1 …

This tutorial paper provides a foundation for integrating probabilistic shaping (PS) and
forward error correction (FEC). A layered PS-FEC architecture consisting of a PS encoder …

The past decade has seen many advances in physical layer wireless communication theory
and their implementation in wireless systems. This textbook takes a unified view of the …

Wireless technology is a truly revolutionary paradigm shift, enabling multimedia
communications between people and devices from any location. It also underpins exciting …
