Foreword
This book discusses multi-carrier modulation and spread spectrum techniques, recognized
as  the  most  promising  candidate  modulation  methods  for  the  4th  generation  (4G)  of
mobile communications systems. The authors of this book were the first to propose MC-
CDMA for the next generation of mobile communications, and are still continuing their
contribution  towards  beyond  3G.  Considering  the  requirements  of  4G  systems,  multi-
carrier and spread spectrum systems appear to be the most suitable as they provide higher
flexibility, higher transmission rates, and frequency usage efficiency. This is the first book
on these methods, providing the reader with the fundamentals of the technologies involved
and the related applications.
The book deals with the principles through definitions of basic technologies and the
multipath channel over which the signals are transmitted. It defines MC-CDMA as a fre-
quency PN pattern and MC-DS-CDMA as a straight extension of DS-CDMA; and argues
that these twin asymmetric technologies are most suitable for 4G since MC-CDMA is
suitable for the downlink and MC-DS-CDMA is suitable for the uplink in the cellular
systems. Although MC-CDMA performs better than MC-DS-CDMA, it needs chip syn-
chronization between users, and is therefore difficult to deploy in the uplink. Thus, for
this asymmetric structure it is very important to understand the multi-carrier spread spec-
trum methods. Hybrid multiple access schemes like Multi-Carrier FDMA, Multi-Carrier
TDMA, and Ultra Wide Band systems are discussed as more extended systems. Imple-
mentation issues, including synchronization, channel estimation, and RF issues, are also
discussed in depth. Wireless local area networks, broadcasting transmission, and cellular
mobile radio are shown to realize seamless networking for 4G. Although cellular systems
have  not  yet  been  combined  with  other  wireless  networks,  different  wireless  systems
should be seamlessly combined. The last part of this book discusses capacity and flexi-
bility enhancement technologies like diversity techniques, space–time/frequency coding,
and SDR (Software Defined Radio).
This book greatly assists not only theoretical researchers but also practicing engineers
of the next generation of mobile communications systems.
