There is a phenomenal burst of research activities in mobile cloud
computing systems, which extends cloud computing functions, ser-
vices, and results to the world of future mobile COMMUNICATIONs
applications, and the paradigm of cloud computing and virtualization
to mobile networks. Mobile applications demand greater resources
and improved interactivity for better user experience.

Mobile multimedia communication is increasingly in demand because of the basic need to communi-
cate at any time, anywhere, using any technology. In addition, to voice communication, people have a
desire to access a range of other services that comprise multimedia elements—text, image, animation,
high fidelity audio and video using mobile communication networks. To meet these demands, mobile
communication technologies has evolved from analog to digital, and the networks have passed through
a number of generations from first generation (1G) to fourth generation (4G).

Mobile teleCOMMUNICATIONs emerged as a technological marvel allowing for access to
personal and other services, devices, computation and communication, in any place and
at any time through effortless plug and play. This brilliant idea became possible as the
result of new technologies developed in the areas of computers and COMMUNICATIONs that
were made available and accessible to the user.

One of the very first books published on the social impact of the mobile phone
was Timo Kopomaa’s The City in Your Pocket: Birth of the Mobile Information Society.
The book, published in 2000, was based on research that Kopomaa had under-
taken for Nokia and Sonera as part of his doctoral studies in the Centre for Urban
and Regional Studies at the Helsinki University of Technology. The first line he
writes in the book is peculiar: ‘Mobile communication is not a serious matter’. By
this, we assume he is referring to a view of the world that would regard the mobile
phone as little more than an unremarkable fact of everyday life – a simple play-
thing for the young, or a productivity tool for the business executive and busy
parent.

Do you have a mobile phone? We think you probably do, one way or another. We
would also guess that you might use it for many diff erent things in the course of your
everyday life—as a telephone certainly, but also as an address book, as a clock or
watch, as a camera, or now as a connection to your computer, email and the internet.
Th ere will be a range of people you use it to contact (or not), and various strategies
you use to take calls—or send texts, or take photos, or receive emails, or search online
(or not, in diff erent situations). Th ere are also likely to be a range of social relation-
ships in your life that your mobile phone helps to maintain—or disrupts, or inter-
venes in, or makes possible, or complicates, or just plain helps to handle.

The last decade proved to be hugely successful for the mobile COMMUNICATIONs industry,
characterised by continued and rapid growth in demand, spurred on by new technological
advances and innovative marketing techniques. Of course, when we refer to mobile commu-
nications, we tend to implicitly refer to cellular systems, such as GSM. The plight of the
mobile-satellite industry over the last decade, although eventful, has, at times, been more akin
to an out of control roller coaster ride.

Since the principle of multi-carrier code division multiple access (MC-CDMA) was
simultaneously proposed by Khaled Fazel et al. and Nathan Yee et al. at the IEEE
International Symposium on Personal, Indoor and Mobile Radio COMMUNICATIONs
(PIMRC) in the year 1993, multi-carrier spread spectrum (MC-SS) has rapidly become
one of the most wide spread independent research topics on the field of mobile radio
COMMUNICATIONs. Therefore, the International Workshop on Multi-Carrier Spread
Spectrum (MC-SS) was initiated in the year 1997. Multi-carrier and spread spectrum
systems with their generic air interface and adaptive technologies are considered as
potential candidates to fulfill the requirements of next generation mobile COMMUNICATIONs
systems.

At recent major international conferences on wireless COMMUNICATIONs,
there have been several sessions on beyond third generation (3G) or fourth
generation(4G)mobileCOMMUNICATIONssystems,wheremodulation/demod-
ulation and multiplexing/multiple access schemes related to multicarrier
techniques have drawn a lot of attention. We often met at the conference
venuesandrealizedthatnobookcoveredthebasicsofmulticarriertechniques
to recent applications aiming at the 4G systems. Therefore, we decided to
write a book on multicarrier techniques for 4G mobile COMMUNICATIONs
systems.

Many wireless COMMUNICATIONs channels consist of multiple signal paths from the
transmitter to receiver. This multiplicity of paths leads to a phenomenon known
as multipath fading. The multiple paths are caused by the presence of objects in the
physical environment that, through the mechanisms of propagation, alter the path of
radiated energy. These objects are referred to as scatterers. In the past, researchers
often looked at ways to mitigate multipath scattering, such as in diversity systems.
Multiple-input, multiple-output (MIMO) systems, on the other hand, use multipath
diversity to their advantage; a MIMO system has the ability to translate increased
spatial diversity into increased channel capacity.

European Research Framework programs are public policy instruments designed
to strengthen European competitiveness through cooperation. Although they have
a fixed time frame, determined research themes, and a specific expected impact,
the achievements in research and development (R&D) made by these funded proj-
ects pave the way for a research continuum.
