In this book we Focus on the basic signal processing that underlies current and
future ultra wideband systems. By looking at signal processing in this way we
hope this text will be useful even as UWB applications mature and change or
regulations regarding ultra wideband systems are modified. The current UWB
field is extremely dynamic, with new techniques and ideas being presented at every
communications and signal-processing conference. The basic signal-processing
techniques presented in this text though will not change for some time to come.
Thus, we have taken a somewhat theoretical approach, which we believe is longer
lasting and more useful to the reader in the long term than an up-to-the-minute
summary that is out of date as soon as it is published.

In this first part of the book the Vienna Link Level (LL) Simulators are described.
The first chapter provides basics of LL simulations, introduces the most common
variables and parameters as well as the transceiver structures that are applied in
Long-Term Evolution (LTE) and Long-Term Evolution-Advanced (LTEA). We
Focus here mostly on the Downlink (DL) of LTE as most results reported in later
chapters are related to DL transmissions.

The Focus of this book is on developing computational algorithms for transmit wave-
form design in active sensing applications, such as radar, sonar, communications and
medical imaging. Waveforms are designed to achieve certain desired properties, which
are divided into three categories corresponding to the three main parts in the book,
namely good aperiodic correlations, good periodic correlations and beampattern match-
ing.

The use of optical free-space emissions to provide indoor wireless commu-
nications has been studied extensively since the pioneering work of Gfeller
and Bapst in 1979 [1]. These studies have been invariably interdisciplinary in-
volving such far flung areas such as optics design? indoor propagation studies?
electronics design? communications systems design among others. The Focus
of this text is on the design of communications systems for indoor wireless
optical channels. Signalling techniques developed for wired fibre optic net-
works are seldom efficient since they do not consider the bandwidth restricted
nature of the wireless optical channel.

This book is concerned with integrated circuits and systems for wireless and
mobile communications. Circuit techniques and implementation of reconfigurable
low-voltage and low-power single-chip CMOS transceivers for multiband and multi-
mode universal wireless communications are the Focus of the book. Applications
encompass both long-range mobile cellular communications (GSM and UMTS)
and short-range wireless LANs (IEEE802.11 and Bluetooth). Recent advances in
research into transceiver architecture, RF frontend, analogue baseband, RF CAD
and automatic testing are reported.

Resource allocation is an important issue in wireless communication networks. In
recent decades, cognitive radio technology and cognitive radio-based networks have
obtained more and more attention and have been well studied to improve spectrum
utilization and to overcomethe problem of spectrum scarcity in future wireless com-
munication systems. Many new challenges on resource allocation appear in cogni-
tive radio-based networks. In this book, we Focus on effective solutions to resource
allocation in several important cognitive radio-based networks, including a cogni-
tive radio-basedopportunisticspectrum access network, a cognitiveradio-basedcen-
tralized network, a cognitive radio-based cellular network, a cognitive radio-based
high-speed vehicle network, and a cognitive radio-based smart grid.

With the proliferation of cloud computing and Internet online services, more and
more data and computation are migrated to geographical distributed Internet data
centers (IDCs), which can provide reliability, management, and cost benefits.
However, IDC operators encounter several major problems in IDC operations, such
as huge energy consumption and energy cost, and high carbon emission. To deal
with the above problems, IDC operators have to efficiently manage the way of
energy consumption and energy supply. Considering the potential of smart grid, we
Focus on the energy management of IDCs in smart grid from several perspectives,
i.e., power outage, carbon emission, heterogeneous service delay guarantees, and
operation risk.

Since its release, Arduino has become more than just a development platform; it has become a culture built around
the idea of open source and open hardware, and one that is reimagining computer science and education. Arduino has
opened hardware development by making the starting skills easy to obtain, but retaining the complexities of real-world
application. This combination makes Arduino a perfect environment for school students, seasoned developers, and
designers. This is the first Arduino book to hold the title of “Pro,” and demonstrates skills and concepts that are used by
developers in a more advanced setting. Going beyond projects, this book provides examples that demonstrate concepts
that can be easily integrated into many different projects and provide inspiration for future ones. The Focus of this book
is as a transition from the intermediate to the professional.

This book will discuss the topic of Control Systems, which is an interdisciplinary engineering
topic. Methods considered here will consist of both "Classical" control methods, and
"Modern" control methods. Also, discretely sampled systems (digital/computer systems) will
be considered in parallel with the more common analog methods. This book will not Focus
on any single engineering discipline (electrical, mechanical, chemical, etc.), although readers
should have a solid foundation in the fundamentals of at least one discipline.

The goal of this text is Focus on a core subset of the natural language processing, unified
by the concepts of learning and search. A remarkable number of problems in natural
language processing can be solved by a compact set of methods:
