Over the past few decades, wireless communications and networking have witnessed an
unprecedented growth, and have become pervasive much sooner than anyone could have
predicted. For example, cellular wireless networks are expected to become the dominant
and ubiquitous telecommunication means in the next few decades. The widespread
success of cellular and WLAN systems prompts the development of advanced wireless
systems to provide access to information services Beyond voice such as telecommuting,
video conferencing, interactive media, real-time internet gaming, and so on, anytime
and anywhere.

While teaching classes on digital transmission and mobile communications for
undergraduate and graduate students, I was wondering if it would be possible to
write a book capable of giving them some insight about the practical meaning of the
concepts, Beyond the mathematics; the same insight that experience and repetitive
contact with the subject are capable to construct; the insight that is capable of build-
ing the bridge between the theory and how the theory manifests itself in practice.

The rapid growth in mobile communications has led to an increasing demand for wide-
band high data rate communications services. In recent years, Distributed Antenna
Systems (DAS) has emerged as a promising candidate for future (Beyond 3G or 4G)
mobile communications, as illustrated by projects such as FRAMES and FuTURE. The
architecture of DAS inherits and develops the concepts of pico- or micro-cell systems,
where multiple distributed antennas or access points (AP) are connected to and con-
trolled by a central unit.

When we started thinking about writing the first edition of this book a few years ago, we had been
working together for more than five years on the borderline between propagation and signal processing.
Therefore, it is not surprising that this book deals with propagation models and design tools for MIMO
wireless communications. Yet, this book should constitute more than a simple combination of these
two domains. It hopefully conveys our integrated understanding of MIMO, which results from endless
controversial discussions on various multi-antenna related issues, as well as various interactions with
numerous colleagues. Obviously, this area of technology is so large that it is Beyond our aim to cover all
aspects in details. Rather, our goal is to provide researchers, R&D engineers and graduate students with
a comprehensive coverage of radio propagation models and space–time signal processing techniques
for multi-antenna, multi-user and multi-cell networks.

Mobile and wireless application development has come a long way in the past few
years. It has progressed Beyond the hype of wireless Web applications for consumers
to the reality of high-value mobile applications for corporate users. Opportunities
abound for creating new mobile and wireless applications that provide vital benefits to
any business. A sampling of these benefits includes increased worker productivity,
reduced processing costs, heightened accuracy, and competitive advantage. In contrast
is the concern that developing mobile and wireless applications will involve many new
technologies and concepts that many corporate developers are still learning to use.

With the rapid growth of the wireless mobile applications, wireless voice has
begun to challenge wireline voice, whereas the desire to access e-mail, surf the
Web or download music (e.g., MP3) wirelessly is increasing for wireless data.
While second generation (2G) cellular wireless systems, such as cdmaOne1,
GSM2 and TDMA3, introduced digital technology to wireless cellular systems
to deal with the increasing demand for wireless applications, there is still the
need for more spectrally efficient technologies for two reasons. First, wireless
voice capacity is expected to continue to grow. Second, the introduction of
high-speed wireless data will require more bandwidth.

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.
