书籍 3G,+4G+and+Beyond–BRINGING NETWORKS
In recent years, cellular voice networks have transformed into powerful packet-switched
access networks for both voice communication and Internet access. Evolving Universal
Mobile Telecommunication System (UMTS) networks and first Long Term Evolution
(LTE) installations now deliver bandwidths of sev ...
书籍 802.11n A Survival Guide
A decade ago, I first wrote that people moved, and networks needed to adapt to the
reality that people worked on the go. Of course, in those days, wireless LANs came
with a trade-off. Yes, you could use them while moving, but you had to trade a great
deal of throughput to get the mobility. Although ...
书籍 A Foundation in Digital Communication
Without conceding a blemish in the first edition, I think I had best come clean
and admit that I embarked on a second edition largely to adopt a more geometric
approach to the detection of signals in white Gaussian noise. Equally rigorous, yet
more intuitive, this approach is not only student-friend ...
书籍 Adaptive Antennas and Receivers
Homogeneous Partitioning of the Surveillance Volume discusses the
implementation of the first of three sequentially complementary approaches for
increasing the probability of target detection within at least some of the cells of
the surveillance volume for a spatially nonGaussian or Gaussian “noise ...

I suppose. The first two reasons and probably the most important are my love of flying and
my love of radio engineering. This may sound rather dull but I love flying in any machine be
it balloon, glider, propeller aircraft, m ...
书籍 Ambient Networks
One traditional view of how wireless networks evolve is of a continuous, inevitable progres-
sion to higher link speeds, combined with greater mobility over wider areas. This standpoint
certainly captures the development from first and second generation cellular systems focused
on voice support, and ...
书籍 Antennas and Propagation
This book has grown out of my teaching and research at the University of Surrey and out of
my previous experiences in companies such as Philips, Ascom and Motorola. It is
primarily intended for use by students in master’s level and enhanced final-year under-
graduate courses who are specialising in ...

The aim of this book, the first of two volumes, is to present selected research that
has been undertaken under COST Action IC0902 ‘‘Cognitive Radio and Net-
working for Cooperative Coexistence of Heterogeneous Wireless Networks’’
(http://newyork.ing.uniroma1.it/IC0902/). COST (European Cooperati ...

Today’s wireless services have come a long way since the roll out of the
conventional voice-centric cellular systems. The demand for wireless access
in voice and high rate data multi-media applications has been increasing.
New generation wireless communication systems are aimed at accommodating

In 2005, when the world crossed-over to Web 2.0, business professionals and managers in
every industry – from traditional retail to high tech media and telecom – felt the first powerful
tremors of the strategic shifts taking place, sweeping away traditional business models and
