Power+Electronic+Modules+Design+Manufacture
A power semiconductor module is basically a power circuit of different<br />
materials assembled together using hybrid technology, such as semiconduc-<br />
tor chip attachment, wire bonding, encapsul
Electromagnetic+Transients+in+Power+Cables
For more than a century, overhead lines have been the most commonly used<br />
technology for transmitting electrical energy at all voltage levels, especially on the<br />
highest levels. However, in
RESTful+Rails+Development+Building
This book is focused on designing and developing Representational State Transfer (REST)<br />
platforms in Rails. REST is the architectural style of the Web, consisting of a set of<br />
constraints t
Bio-MEMS - Technologies and Applications
Applications of microelectromechanical systems (MEMS) and microfabrica-<br />
tion have spread to different fields of engineering and science in recent years.<br />
Perhaps the most exciting developme
Wireless+Communications+over+MIMO+Channels
Mobile radio communications are evolving from pure telephony systems to multimedia<br />
platforms offering a variety of services ranging from simple file transfers and audio and<br />
video streaming
Wireless Communications 2nd Edition
n the first part of this book, we give an introduction to the basic applications of wireless com-<br />
munications, as well as the technical problems inherent in this communication paradigm. After a<
Wavelength Division Multiplexing
Wavelength division multiplexing (WDM) refers to a multiplexing and transmission<br />
scheme in optical telecommunications fibers where different wavelengths, typically<br />
emitted by several laser
UMTS+Performance+Measurement+A+Practical+Guide
Having dealt with in-depth analysis of SS#7, GSM and GPRS networks I started to monitor<br />
UTRAN interfaces approximately four years ago. Monitoring interfaces means decoding<br />
the data capture
Telecommunication+Systems
Intensive development of digital technologies coincided in time with the beginning<br />
of the new era in telecommunications. It made possible to formalize many proce-<br />
dures of data exchange an
Software+Defined+Radio
Until the mid-1990s most readers would probably not have even come across the term soft-<br />
ware defined radio (SDR), let alone had an idea what it referred to. Since then SDR has made<br />

Simulation of Communication Systems
Since the first edition of the book was published, the field of modeling and simulation of<br />
communication systems has grown and matured in many ways, and the use of simulation as a<br />
day-to-d
Reconfigurable+Mobile+Radio+Systems
Digital mobile wireless communication and the Internet have undergone a<br />
fantastic growth in the last few years and, despite originating from two different<br />
worlds, they are converging. This
Radio+Resource+Management
Wireless communications and networking technology are advancing at a very rapid<br />
pace. Newer technologies and standards are evolving to serve the ever-increasing num-<br />
ber of users demanding
Protocol Engineering
Communication protocols – for short protocols – form the basis for the opera-<br />
tion of computer networks and telecommunication systems. They are behavior<br />
conventions which describe how comm
Propagation Handbook for Wireless Communication
Wireless means different things to different people. For this book, it refers<br />
to the radio systems that provide point-to-point, point-to-multipoint, and<br />
Earth-space communications over tra
Multi-Standard+CMOS+Wireless+Receivers
Wireless communication is witnessing tremendous growth with great proliferation of different standards covering wide ,local and personal area networks
Modeling and Tools for Network Simulation
In general there are three different techniques for performance evaluation of<br />
systems and networks: mathematical analysis, measurements, and computer<br />
simulation. All these techniques have
Mobile+Channel+Characteristics
At the macroscopic level of system layout, the most important issue is path loss. In the<br />
older mobile radio systems that are limited by receiver noise, path loss determines SNR and<br />
the max
Mobile and Wireless Communications
There are few technologies that have had a more profound effect on people’s lives<br />
than mobile communications. As recently as twenty years ago no one had a mobile<br />
phone, while today 1.4 bil
