In this updated and expanded edition of her excellent telecommunications primer,
Lili explains in just the right detail everything you need to know to become
fluent in this most important and fascinating industry. Besides including a
satisfying amount of expert technical detail, the book also discusses equally
crucial aspects of how communications technology affects society, culture, and
politics. Electronic communications is changing the world for the better; learn
from Lili's expertise how you, too, can participate in the revolution." Steve Riley, senior security strategist, Microsoft

the development of modern mobile communications. It provides a suitable base for enhanced
services due to increased data throughput and lower latency figures, and also gives extra
impetus to the modernization of telecom architectures. The decision to leave the circuit-

of LTE/SAE is concrete evidence of this GLOBAL trend.
Second-generation telecommunication systems, such as the GLOBAL System for Mobile
Communications (GSM), enabled voice traffic to go wireless: the number of mobile phones
exceeds the number of landline phones and the mobile phone penetration is approaching
100% in several markets. The data-handling capabilities of second-generation systems are
limited, however, and third-generation systems are needed to provide the high bit-rate
services that enable high-quality images and video to be transmitted and received, and to
provide access to the Web with higher data rates.
Recent advancements in nanotechnology (NT) materials and growth of micro/
nanotechnology have opened the door for potential applications of microelectro-
mechanical systems (MEMS)- and NT-based sensors and devices. Such sensors and
devices are best suited for communications, medical diagnosis, commercial, military,
aerospace, and satellite applications. This book comes at a time when the future and
well-being of Western industrial nations in the twenty-first century’s GLOBAL eco-
nomy increasingly depend on the quality and depth of the technological innovations
they can commercialize at a rapid pace.
In this age of science and technology, the GLOBAL economy has developed so much that our
lifestyles are now extremely modernized and developed. In some ways, modern society
seems to have reached the utmost state of advancement in various areas, including eco-
nomic development, science and technology pursuit, and the utilization of the given nat-
ural environment. However, it is important to consider approaches that may allow human
beings to stay longer on the Earth while enjoying fulfilling and peaceful daily lives.
Power Electronics is one of modern and key technologies in Electrical and
Electronics Engineering for green power, sustainable energy systems, and smart
grids. Especially, the transformation of existing electric power systems into smart
grids is currently a GLOBAL trend. The gradual increase of distributed generators in
smart grids indicates a wide and important role for power electronic converters in
the electric power system, also with the increased use of power electronics devices
(nonlinear loads) and motor loadings, low cost, low-loss and high-performance
shunt current quality compensators are highly demanded by power customers to
solve current quality problems caused by those loadings.

With GLOBAL drivers such as better energy
consumption, energy efficiency and reduction of
greenhouse gases, CO 2 emission reduction has become
key in every layer of the value chain. Power Electronics
has definitely a role to play in these thrilling challenges.
From converters down to compound semiconductors,
innovation is leading to breakthrough technologies. Wide
BandGap, Power Module Packaging, growth of Electric
Vehicle market will game change the overall power
electronic industry and supply chain. In this presentation
we will review power electronics trends, from
technologies to markets.
Software-defined radios (SDRs) have been around for more than a decade. The
first complete GLOBAL Positioning System (GPS) implementation was described
by Dennis Akos in 1997. Since then several research groups have presented their
contributions. We therefore find it timely to publish an up-to-date text on the sub-
ject and at the same time include Galileo, the forthcoming European satellite-
based navigation system. Both GPS and Galileo belong to the category of GLOBAL
Navigation Satellite Systems (GNSS).
This book is about GLOBAL navigation satellite systems (GNSS), their two main instru-
ments, which are a receiver and a simulator, and their applications. The book is based on
an operational off-the-shelf real-time software GNSS receiver and off-the-shelf GNSS
signalsimulator.Theacademicversionsofthesetoolsarebundledwiththisbookandfree

The purpose of this book is to present detailed fundamental information on a
GLOBAL positioning system (GPS) receiver. Although GPS receivers are popu-
larly used in every-day life, their operation principles cannot be easily found
in one book. Most other types of receivers process the input signals to obtain
the necessary information easily, such as in amplitude modulation (AM) and
frequency modulation (FM) radios. In a GPS receiver the signal is processed
to obtain the required information, which in turn is used to calculate the user
position. Therefore, at least two areas of discipline, receiver technology and
navigation scheme, are employed in a GPS receiver. This book covers both
areas.
