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.
Wireless communications, together with its applications and underlying technologies, is
among today’s most active areas of technology development. The very rapid pace of im-
provements in both custom and programmable integrated circuits for signal processing ap-
plications has led to the justfiable view of advanced signal processing as a key enabler of the
aggressively escalating capacity demands of emerging wireless systems. Consequently, there
has been a tremendous and very widespread effort on the part of the research community
to develop novel signal processing techniques that can fulfill this promise.
The wide deployment of wireless networks and mobile technologies, along with the
significant increase in the number of mobile device users, have created a very strong
demand on various wireless-based, mobile-based software application systems and
enabling technologies. This not only provides many new business opportunities and
challenges to wireless and networking service providers, mobile technology ven-
dors, and software industry and solution integrators, butalso changes and enhances
people’s lives in many areas, including communications, information sharing and
exchange, commerce, home environment, education, and entertainment. Business
organizations and government agencies face new pressure fortechnology updatesto
upgrade their networking infrastructures with wireless connectivity to enhance
enterprise-oriented systems and solutions.
Describing the relevant detection and estimation theory, this detailed guide provides
the background knowledge needed to tackle the design of practical WLAN positioning
systems. It sets out key system-level challenges and design considerations in increasing

and presents experimental results.
District energy (DE) systems use central heating and/or cooling facilities to provide
heating and/or cooling services for communities. The advantages of district energy
over conventional heating and cooling include improved efficiency, reliability and
safety, reduced environmental impact, and for many situations better economics.
DE systems can be particularly beneficial when integrated with cogeneration plants
for electricity and heat, i.e., with combined heat and power (CHP) plants. One of
the main impediments to increased use of cogeneration-based district energy is a
lack of understanding of the behavior of integrated forms of such systems. This
book is aimed at providing information on district energy and cogeneration tech-
nologies, as well as systems that combine them.
The use of renewable energy systems, such as wind power, hydropower, tidal
power, solar power, geothermal power and biomass burn is growing. Research in
electric power generation from renewable sources is continuously expanding and
stands for an area of high technological and financial importance. The implemen-
tation of new technologies for the functioning and management of renewable
energy systems will help to further develop the renewable energy sector.
Switched systems are embedded devices widespread in industrial
applications such as power electronics and automotive control. They
consist of continuous-time dynamical subsystems and a rule that
controls the switching between them. Under a suitable control rule, the
system can improve its steady-state performance and meet essential
properties, such as safety and stability, in desirable operating zones.
RFID networks are currently recognized as one a research area of priority. Research
activities related to RFID technology have been booming recently. A number of ongoing
projects are being funded in Europe, Asia, and North America. According to leading
market analysts, the development of the RFID market is projected to increase from
approximately $3 billion in 2005 to $25 billion in 2015. Several countries have dedicated
innovation programs to support and develop RFID systems and related technologies: the
RFID initiative in Taiwan, Ubiquitous Japan and the NSF SBIR program in the USA.
The EU has recently advertised its Strategic Research Roadmap concerning the Internet of
Things, which first of all refers to the RFID technology before being extended to commu-
nicating devices as in M2M (Machine to Machine). In this roadmap, several application
domains have been identified:
Control Systems Engineering is an exciting and challenging field and is a
multidisciplinary subject. This book is designed and organized around the concepts of control
systems engineering using MATLAB, as they have been developed in the frequency and time
domain for an introductory undergraduate or graduate course in control systems for engineer-
ing students of all disciplines.
Control systems are becoming more important every day. At the beginning, the in-
dustry used sequential controls for solving a lot of industrial applications in control
systems, and then the linear systems gave us a huge increase in applying automatic
linear control on industrial application. One of the most recent methods for control-
ling industrial applications is intelligent control, which is based on human behavior
or concerning natural process.
