Coding for Optical Channels

In order to adapt to the ever-increasing demands for high-speed transmission and distance-independent connectivity, todays network operators are implementing 100 Gb/s per dense wavelength division multiplexing (DWDM) channel. At those data rates, the performance of fiber-optic communication systems is degraded significantly due to intra- and inter-channel fiber nonlinearities, polarization-mode dispersion (PMD), and chromatic dispersion. In order to deal with these channel impairments, novel advanced techniques in modulation, detection, coding and signal processing are needed.

This groundbreaking book represents a coherent and comprehensive introduction to the fundamentals of optical communications, digital signal processing (DSP), and coding for optical channels. This book:

• Is the first to integrate the fundamentals of coding theory and DSP with the fundamentals of optical communication;
• Provides detailed coverage of joint coding and modulation for optical communications;
• Presents turbo equalization for joint iterative channel equalization and soft decoding on optical channels;
• Provides in-depth coverage of codes on graphs, including LDPC and turbo codes, and describes their application to optical channels;
• Includes coverage of both fiber-optics and free-space optical (FSO) channels;
• Is the first to cover the channel capacity of fiber-optic communication systems;
• Is the first to describe constrained coding for optical channels.
