Coding for Optical Channels

In order to adapt to the ever-increasing demands of telecommunication needs, today’s network operators are implementing 100 Gb/s per dense wavelength division multiplexing (DWDM) channel transmission. At those data rates, the performance of fiberoptic 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 those channel impairments, novel advanced techniques in modulation and detection, coding and signal processing are needed.

This unique book represents a coherent and comprehensive introduction to the fundamentals of optical communications, signal processing and coding for optical channels. It is the first to integrate the fundamentals of coding theory with the fundamentals of optical communication.

In order to adapt to the ever-increasing demands for high-speed transmission and distance-independent connectivity, today’s 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.
