The telecommunications industry has seen a rapid boost within the last decade. New realities
and visions of functionalities in various telecommunications networks have brought forward the
concept of next-generation networks (NGNs). The competitions among operators for support-
ing various services, ...
Performance analysis belongs to the domain of applied mathematics. The
major domain of application in this book concerns telecommunications sys-
tems and networks. We will mainly use stochastic analysis and probability
theory to address problems in the performance evaluation of telecommuni-
cations ...
Recent decades have shown a tremendous expansion of the Internet. The number of
connected terminals has increased by orders of magnitude, traffic has grown exponen-
tially, coverage has become ubiquitous and worldwide, and today’s sophisticated Web
2.0 applications are increasingly providing servic ...
Soon after Samuel Morse’s telegraphing device led to a deployed electri-
cal telecommunications system in 1843, waiting lines began to form by those
wanting to use the system. At this writing queueing is still a significant factor in
designing and operating communications services, whether they are ...
This book provides the essential design techniques for radio systems that
operate at frequencies of 3 MHz to 100 GHz and which will be employed in
the telecommunication service. We may also call these wireless systems,
wireless being synonymous with radio, Telecommunications is a vibrant indus-
try, ...
We are currently witnessing an increase in telecommunications norms and
standards given the recent advances in this domain. The increasing number of
normalized standards paves the way for an increase in the range of offers and
services available for each consumer. Moreover, the majority of available ...
Wireless communications and networking technology are advancing at a very rapid
pace. Newer technologies and standards are evolving to serve the ever-increasing num-
ber of users demanding different types of mobile applications and services. Research
and development activities on wireless technology ...
Commoditization is a serious threat to the telecommunications industry. Most CSPs offer
similar services at rates designed to win what has become a price war. As a result, many
face decreasing margins and difficulty sustaining differentiation based on prices or
products alone. On top of commoditizat ...
This paper presents a Hidden Markov Model (HMM)-based speech
enhancement method, aiming at reducing non-stationary noise from speech
signals. The system is based on the assumption that the speech and the noise
are additive and uncorrelated. Cepstral features are used to extract statistical
informati ...
The first edition of this book was published in 1992. Nine years later it had become
clear that a second edition was required because of the rapidly changing nature of
telecommunication. In 1992, the Internet was in existence but it was not the
household word that it is in the year 2001. Cellular te ...
