书籍 Principles+of+Communication+Systems+Simulation
This book is a result of the recent rapid advances in two related technologies: com-
munications and computers. Over the past few decades, communication systems
have increased in complexity to the point where system design and performance
analysis can no longer be conducted without a significant lev ...
书籍 Radio+Protocols+for+LTE+and+LTE-A
It was only a few years ago that “ubiquitous connectivity” was recognized as the future of
wireless communication systems. In the era of ubiquitous connectivity, it was expected that
the broadband mobile Internet experience would be pervasive, and seamless connectivity on
a global scale would be n ...
书籍 RF Engineering
The first gem of wisdom I ever acquired about consulting, obtained many years ago
from a former schoolmate, was to ensure that everything is plugged in: no continuity, no
data. Wires carry voltages and currents from one place to another. Their behavior is
reasonably simple and predictable—at least ...
书籍 The 3G IP Multimedia Subsystem (IMS)
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 ...
书籍 The+Mobile+Radio+Propagation+Channel
Some tine ago it become apparent the the first edition of this book was rapidly approaching its sell-by date,since many aspects needed revise.There were two obvious courses of action : to forget the whole thing and concentrate my energies on other pursuits such as golf or fishing, or to embark on a ...
书籍 UMTS+Performance+Measurement+A+Practical+Guide
Having dealt with in-depth analysis of SS#7, GSM and GPRS networks I started to monitor
UTRAN interfaces approximately four years ago. Monitoring interfaces means decoding
the data captured on the links and analysing how the different data segments and messages
are related to each other. In general ...
书籍 Electro Static Discharge Understand
Static electricity is the most ancient form of electricity known to humans. More
than 2000 years ago, the Greeks recognized the attraction between certain mate-
rials when they were rubbed together; indeed, the word electricity comes from
the Greek elektron, which means amber. During the seventeenth ...
书籍 Coriolis Vibratory Gyroscopes
Thanks to the advances in micromachining fabrication technologies and significant
cost reduction due to mass production, miniature sensors of angular rate, or
gyroscopes, found their way into the everyday life of every user of modern gadgets,
such as smart phones, tablets or even wristwatches. Often ...
书籍 Intro To MEMS Eng
A few years ago I stood before an audience at a customer’s facility
explaining the merits of micromachining technology. The small
conference room was packed, and all ears were attentive. Everyone was
eager to learn about thismysteriousbuzzword, “MEMS.”Although many
in the audience were nodding in ...
书籍 Power Electronics Handbook, 3 Edition
There have been many developments in the field of power electronics since
the  publication of  the  second edition, almost  five  years  ago. Devices have
become  bigger and better  -  bigger silicon die, and current and voltage
ratings. However, semicond ...
