Book Description
Code-division multiple access (CDMA) technology has been widely adopted in cell phones. Its astonishing success has led many to evaluate the promise of this technology for optical networks. This field has come to be known as Optical CDMA (OCDMA). Surveying the field from its infancy to the current state, Optical Code Division Multiple Access: Fundamentals and Applications offers the first comprehensive treatment of OCDMA from technology to systems. The book opens with a historical perspective, demonstrating the growth and development of the technologies that would eventually evolve into today's optical networks. Building on this background, the discussion moves to coherent and incoherent optical CDMA coding techniques and performance analysis of these codes in fiber optic transmission systems. Individual chapters provide detailed examinations of fiber Bragg grating (FBG) technology including theory, design, and applications; coherent OCDMA systems; and incoherent OCDMA systems. Turning to implementation, the book includes hybrid multiplexing techniques along with system examples and conversion techniques to connect networks that use different multiplexing platforms, state-of-the-art integration technologies, OCDMA network security issues, and OCDMA network architectures and applications, including a look at possible future directions. Featuring contributions from a team of international experts led by a pioneer in optical technology, Optical Code Division Multiple Access: Fundamentals and Applications places the concepts, techniques, and technologies in clear focus for anyone working to build next-generation optical networks.

Book Description
Optical code division multiple access (OCDMA) communication network technology will play an important role in future optical networks, such as optical access and metropolitan area networks. OCDMA technology can also be applied to implement optical signal multiplexing and label switching on backbone networks. Optical Code Division Multiple Access Communication Networks - Theory and Applications introduces the code theory of OCDMA, the methods and technologies of OCDMA encoding and decoding, the theory and methods of analyzing OCDMA systems with various receiver models and realizing multiple-class services with different bit rates and QoS. In addition, OCDMA network architectures, protocols and applications are discussed in detail. The up-to-date theoretical and experimental results on OCDMA systems and networks are also reported. A large number of encoding/decoding examples and many analysis and simulation results of code and system performances are given. It is a valuable text and/or reference book for postgraduates majoring in telecommunication and photonics to obtain a well-knit theoretical foundation and for engineers in R&D and management of optical communications. Dr. Yin is an Associate Professor of the School of Electronics Engineering and Computer Science at Peking University, China, and was a Visiting Research Fellow of Optoelectronics Research Centre (ORC) at University of Southampton, UK. Dr. Richardson is a Professor for optical communications and Deputy Director of ORC at University of Southampton, UK, and is responsible for much of the ORC's fiber related activities.

Book Description
In this thesis, firstly we have reviewed both previous and current state of optical CDMA (OCDMA) technologies. Search for appropriate spreading codes is one of the main challenges of OCDMA applications and hence is an important topic which is heavily addressed in the literature. Existing codes have restrictions on code-lengths, weights and correlation properties where the number of generated codes is severely limited. Secondly, we have paid a particular attention to proposing a novel spreading code, hereby referred to as Double Padded Modified Prime Code (DPMPC) which suppresses the multiple-access interference and also enhances the network capacity. Then, we have applied the DPMPC to both coherent and incoherent time-spreading OCDMA transceivers and analysed their overall performances. We have also proposed novel transceivers which are power-efficient, simple and able to accommodate great number of simultaneous users. Accordingly, an advanced two-dimensional frequency-polarization modulation for OCDMA has been introduced, for the first time, to elevate the system security as well as the performance. Finally, the application of OCDMA in the passive optical network leading to the OCDMA-PON architecture has been established including the optical line terminal and network units. Since Internet protocol is currently the dominant network protocol, IP-over-OCDMA network node configuration ha.
