Providing straightforward practical guidance, this highly accessible resource presents today's most advanced topics on photonic communications. Professionals get the latest details on 5th generation photonic systems that can be readily applied to their projects in the field. Moreover, the book provides valuable, time-saving tools for network simulation and modeling. Engineers find in-depth coverage of optical signal transmission systems and networks. The book includes coverage of a wide range of critical methods and techniques, such as MIMO (multiple-input and multiple-output), OFDM (Orthogonal frequency-division multiplexing), and advanced modulation and coding. Practitioners will find detailed discussions on the basic principles and applications of high-speed digital signal processing. Other key topics include advanced concepts on coded-modulation, turbo equalization, polarization-time coding, spatial-domain-based modulation and coding, and multidimensional signaling. This comprehensive book includes a complete set of problems at the end of each chapter to help readers master the material.
