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.

Soon after Samuel Morse’s telegraphing device led to a deployed electri-
cal telecommunications system in 1843, waiting lines began to form by those
wanting to use the system. At this writing queueing is still a significant factor in
designing and operating communications services, whether they are provided
over the Internet or by other means, such as circuit switched networks.

The fi rst edition of this book came about because Regina Lundgren had always been
fascinated with communication. She started writing novels in the third grade. When she
was asked on her fi rst day at the University of Washington what she hoped to do with her
degree in scientifi c and technical communication, she replied, “I want to write environ-
mental impact statements.” When Patricia Clark hired her to work at the Pacifi c Northwest
National Laboratory to do just that, she was overjoyed.

Before I can present design concepts or tactical wireless communications and network
challenges, I feel the need to mention the challenges of writing for a field where some
information is not available for public domain and cannot be included in this book’s context.
Another challenge is the use of military jargon and the extensive number of abbreviations
(and abbreviations of abbreviations!) in the field. Engineering books are naturally dry, and I
have attempted to make it light by presenting the concepts in layman’s terms before diving
into the technical details. I am structuring this book in such a way as to make it useful for
a specialized graduate course in tactical communications and networking, or as a reference
book in the field.

When 3GPP started standardizing the IMS a few years ago, most analysts expected the
number of IMS deploymentsto grow dramatically as soon the initial IMS specifications were
ready (3GPP Release 5 was functionallyfrozenin the first half of 2002and completedshortly
after that). While those predictions have proven to be too aggressive owing to a number of
upheavals hitting the ICT (Information and Communications Technologies) sector, we are
now seeing more and more commercial IMS-based service offerings in the market. At the
time of writing (May 2008), there are over 30 commercial IMS networks running live traffic,
addingup to over10million IMS users aroundthe world; the IMS is beingdeployedglobally.
In addition, there are plenty of ongoing market activities; it is estimated that over 130 IMS
contracts have been awarded to all IMS manufacturers. The number of IMS users will grow
substantially as these awarded contracts are launched commercially. At the same time, the
number of IMS users in presently deployed networks is steadily increasing as new services
are introduced and operators running these networks migrate their non-IMS users to their
IMS networks.

In writing this text my intention was to collect together in a single place
practical predictive modeling techniques, ideas and strategies that have been
proven to work but which are rarely taught in business schools, data science
courses or contained in any other single text.

Although doing science is at the heart of discovery, the effort would have
very limited consequence in the long term without writingscience. As a social
enterprise that depends on collaboration, scientific inquiry requires its practi-
tioners to write on a regular basis. From time to time, some members of the
scientific community have been critical of the overall quality of writing by re-
searchers.

Building a robot and enabling it to sense its environment is a wonderful way to
take your Arduino knowledge to the next level. In writing this book, I have brought
together my love for invention and my experience with electronics, robotics and
microcontrollers. I hope you have as much pleasure building and enhancing your
robot as I did developing the techniques contained in this book.

The idea of writing this book arose from the need to investigate the main principles of
modern power electronic control strategies, using fuzzy logic and neural networks, for
research and teaching. Primarily, the book aims to be a quick learning guide for
postgraduate/undergraduate students or design engineers interested in learning the
fundamentals of modern control of drives and power systems in conjunction with the
powerful design methodology based on VHDL.
