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

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 …

The FEC limit paradigm is the prevalent practice for designing optical communication
systems to attain a certain bit error rate (BER) without forward error correction (FEC). This …

In this paper, achievable information rates (AIR) for fiber optical communications are
discussed. It is shown that AIRs such as the mutual information and generalized mutual …

We review the most recent advanced concepts and methods employed in the cutting-edge
spectrally efficient coherent fiber-optic transoceanic transmission systems, such as …

The choice of modulation schemes is a fundamental building block of wireless
communication systems. As a key component of physical layer design, they critically impact …

The principle of coding in the signal space follows directly from Shannon's analysis of
waveform Gaussian channels subject to an input constraint. The early design of …

This paper reviews the performance of optimized modulation formats in two, four, and eight
dimensions. We present performance (lower bounds) for higher dimensions by exploiting …

Presenting a thorough overview of bit-interleaved coded modulation (BICM), this book
introduces the tools for the analysis and design of BICM transceivers. It explains in details …
