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* Contains many new and previously unpublished research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.

Over de auteur
Professor HH Chen is the Director of the Institute of
Communications Engineering at the National Sun Yat-Sen University
in Taiwan. He is also an Honorable Guest Professor at
Zhejiang University in China and a Visiting Professor at the
Chinese University of Hong Kong.
Dr. Chen received his BSc and MSc degrees from Zhejiang
University, China, and his Ph D degree from the University of Oulu,
Finland, in 1982, 1985 and 1990, respectively, all in Electrical
Engineering. Since then he has held a number of posts within
academia in Finland, Taiwan, Germany, Japan and Hong Kong.
His research efforts in spread spectrum and CDMA communication
systems has resulted in nine US, Finnish and Taiwanese patents,
most of which have been licensed to industry for commercial
applications. He has served and been serving as the Editor of the
special issues of IEEE Journal on Selected Areas in Communications
and is a recipient of the numerous research and teaching Awards
from the National Science Council, the Ministry of Education and
other professional associations in Taiwan. He has recently become
the Editor for Asia & the Pacific for the Wiley journal
Wireless Communications & Mobile Computing.
