A transmission system with adjustable data rate for single-carrier coherent optical
transmission is proposed, which enables high-speed transmission close to the Shannon …

Since the introduction of coherent transponders, forward error correction based on soft
decision is now established in optical communication. In this paper, we give a tutorial-style …

Convolutional low-density parity-check (LDPC) ensembles, introduced by Felström and
Zigangirov, have excellent thresholds and these thresholds are rapidly increasing functions …

We investigate spatially coupled code ensembles. For transmission over the binary erasure
channel, it was recently shown that spatial coupling increases the belief propagation …

This tutorial paper presents an overview of advanced FEC and coded modulation (CM) for
optical communications. It describes the following ultra-high-speed optical transport …

We consider a windowed decoding scheme for LDPC convolutional codes that is based on
the belief-propagation (BP) algorithm. We discuss the advantages of this decoding scheme …

Traditional communication theory focuses on minimizing transmit power. However,
communication links are increasingly operating at shorter ranges where transmit power can …

Low-density parity-check (LDPC) convolutional codes are capable of achieving excellent
performance with low encoding and decoding complexity. In this paper, we discuss several …

Error correction coding (ie, channel coding) is a key ingredient of any digital
communications system. In mobile wireless communications, channel codes have evolved …

Spatially coupled codes have been of interest recently owing to their superior performance
over memoryless binary-input channels. The performance is good both asymptotically, since …
