This book focuses heavily on the principles, analysis and
applications of code-division multiple-access (CDMA) techniques in
optical communication systems and networks.
In this book, the authors intimately discuss modern optical
networks and their applications in current and emerging
communication technologies, evaluating the quality, speed and
number of supported services. In particular, principles and
fundamentals of optical CDMA techniques from beginner to advanced
levels are heavily covered. Furthermore, the authors concentrate on
methods and techniques of various encoding and decoding schemes and
their structures, as well as analysis of optical CDMA systems with
various transceiver models including advanced multi-level
incoherent and coherent modulations with the architecture of
access/aggregation networks in mind. Moreover, authors examine
intriguing topics of optical CDMA networking, compatibility with IP
networks, and implementation of optical multi-rate multi-service
CDMA networks.
Key features:
* Expanded coverage of optical CDMA networks, starts from
principles and fundamentals
* Comprehensive mathematical modelling and analysis from signal
to system levels
* Addresses the applications of modern optical networking in the
current and emerging communication technologies
* Greater focus on advanced optical multi-level incoherent and
coherent modulations, spreading codes, and transceiver designs
* Detailed hardware specifications, system-level block diagrams,
and network nodes’ functionalities
This book appeals to researchers, practicing engineers, and
advanced students. It is a practical resource for readers with an
interest in optical communications and networks.
