We propose a novel binary message passing decoding algorithm for product-like codes
based on bounded distance decoding (BDD) of the component codes. The algorithm …

We describe an experimental and numerical comparison of a probabilistically shaped (PS)
4096 QAM signal and a uniformly shaped 1024 QAM signal. Both modulation formats have …

This paper aims to provide a reduced-complexity decoding for satellite communication
systems to enhance system performance and transmission efficiency. By addressing the …

This book is the result of a decade of teaching optical communications to graduate and
advanced undergraduate students. For many years, we taught optical communications …

Neural networks (NNs) inspired by the forward-backward algorithm (FBA) are used as
equalizers for bandlimited channels with a memoryless nonlinearity. The NN-equalizers are …

We consider probabilistic amplitude shaping (PAS) as a means of increasing the spectral
efficiency of fiber-optic communication systems. In contrast to previous works in the …

Forward error correction () is an essential technique required in almost all communication
systems to guarantee reliable data transmission close to the theoretical limits. In this chapter …

The maximum information rates for bandlimited channels with direct detection are achieved
with joint detection and decoding (JDD), but JDD is often too complex to implement. Two …

We propose a modified iterative bounded distance decoding of product codes. The
proposed algorithm is based on exchanging hard messages iteratively and exploiting …

Although forward error-correction (FEC) coding is an essential part of modern fiber-optic
communication systems, it is impractical to implement and evaluate FEC in transmission …
