The Next Generation Cdma Technologies

Future wireless communication systems should be operating mainly, if not completely, on burst data services carrying multimedia traffic.The need to support high-speed burst traffic has already posed a great challenge to all currently available air-link technologies based either on TDMA or CDMA.The first generation CDMA technology has been used in both 2G and 3G mobile cellular standards and it has been suggested that it is not suitable for high-speed burst-type traffic. There are many problems with the first generation CDMA technology, such as its low spreading efficiency, interference-limited capacity and the need for precision power control, etc... 'The Next Generation Technologies' will offer first-hand information on how to make use of various innovative technologies to implement the next generation CDMA technology. As an all-in-one reference for telecommunications engineers, advanced R & D personnels, undergraduate and postgraduate students, this book is must-read material. Addresses various important issues about the next generation CDMA technologies as the major air-link technology for beyond 3G wireless applications. Covers topics from next generation CDMA system modelling to analytical methodology, starting with the basics and progressing to advanced research topics. Contains many new and previously unpublished research results. Introduces many innovative CDMA technologies such as DS/CC-CDMA, OS/CC-CDMA, space-time complementary coding CDMA, M-ary CDMA, optical complementary coded CDMA, etc.

This book presents a comprehensive overview of the latest technology developments in the field of Mobile Communications. It focuses on the fundamentals of mobile communications technology and systems, including the history and service evolution of mobile communications and environments. Further to this, CDMA technology including spread spectrum, orthogonal and PN codes are introduced. Other important aspects are included.

Next Generation Wireless Systems and Networks offers an expert view of cutting edge Beyond 3rd Generation (B3G) wireless applications. This self-contained reference combines the basics of wireless communications, such as 3G wireless standards, spread spectrum and CDMA systems, with a more advanced level research-oriented approach to B3G communications, eliminating the need to refer to other material. This book will provide readers with the most up-to-date technological developments in wireless communication systems/networks and introduces the major 3G standards, such as W-CDMA, CDMA2000 and TD-SCDMA. It also includes a focus on cognitive radio technology and 3GPP E-UTRA technology; areas which have not been well covered elsewhere. Covers many hot topics in the area of next generation wireless from the authors’ own research, including: Bluetooth, all-IP wireless networking, power-efficient and bandwidth-efficient air-link technologies, and multi-user signal processing in B3G wireless Clear, step-by-step progression throughout the book will provide the reader with a thorough grounding in the basic topics before moving on to more advanced material Addresses various important topics on wireless communication systems and networks that have emerged only very recently, such as Super-3G technology, 4G wireless, UWB, OFDMA and MIMO Includes a wealth of explanatory tables and illustrations This essential reference will prove invaluable to senior undergraduate and postgraduate students, academics and researchers. It will also be of interest to telecommunications engineers wishing to further their knowledge in this field.

Fourth-Generation Wireless Networks: Applications and Innovations presents a comprehensive collection of recent findings in access technologies useful in the architecture of wireless networks.

th This book contains the best papers of the 5 International Conference on e-Business and Telecommunications (ICETE), which was held in July 2008, in Porto, Portugal. This conference reflects a continuing effort to increase the dissemination of recent research results among professionals who work in the areas of e-business and te- communications. ICETE is a joint international conference integrating four major areas of knowledge that are divided into four corresponding conferences: ICE-B (- ternational Conf. on e-Business), SECRYPT (International Conf. on Security and Cryptography), SIGMAP (Int’l Conf. on Signal Processing and Multimedia) and WINSYS (International Conf. on Wireless Information Systems). The program of this joint conference included several outstanding keynote lectures presented by internationally renowned distinguished researchers who are experts in the various ICETE areas. Their keynote speeches have contributed to heightening the overall quality of the program and significance of the theme of the conference. The conference topic areas define a broad spectrum in the key areas of e-business and telecommunications. This wide-view reporting made ICETE appealing to a global au- ence of engineers, scientists, business practitioners and policy experts. The papers - cepted and presented at the conference demonstrated a number of new and innovative solutions for e-business and telecommunication networks and systems, showing that the technical problems in these closely related fields are challenging and worthwhile - proaching an interdisciplinary perspective such as that promoted by ICETE.

Contains the latest research, case studies, theories, and methodologies within the field of wireless technologies.

What will the future of wireless communications look like? What drives mobile communications systems beyond 3G? In Next Generation Mobile Systems the authors answer these questions and others surrounding the new technologies. The book examines the current research issues driving the wireless world and provides an inclusive overview of how established technologies will evolve to suit next generation mobile systems. While the term ‘4G’ already dominates research in industry and academia, there are still numerous hurdles to take before this ambitious concept can become reality. Acclaimed researchers from NTT-DoCoMo take up the debate of what type of mobile communications will emerge in the post-3G era. Next Generation Mobile Systems: Covers the evolution of IP-based systems and IP mobility. Gives a detailed overview of radio-access technologies and wireless LANs. Explains APIs for mobile systems and IP mobility. Addresses middleware and applications, including terminal platform technologies, multimedia, and wireless web services. Discusses security in future mobile networks, including sections on Cryptographic Algorithms and Protocols for XG, Authentication, Authorization, and Accounting, and Security Policy Enforcement for Downloaded Code. This valuable resource will provide communications engineers, telecommunications managers and researchers in industry and academia with a sound understanding of the future direction of mobile technology.
