Title: | Modern Communications Technology | Volume: | Author(s): | Nataša Živić | Series: | De Gruyter Graduate | Periodical: | | Publisher: | Walter de Gruyter | City: | | Year: | 2016 | Edition: | | Language: | English | Pages (biblio\tech): | XVI+458\475 | ISBN: | 311041337X, 9783110413373 |
This book is written using a decade-long experience in teaching “Fundamentals of
Communications” and “Digital Communications Technology” at the University of
Siegen, Germany. Thus, one part of the material is based on the scripts used for
these lectures, as well as on the scripts for “Cryptographic methods and applications”.
Another part of the presented material is based on the author’s working experience,
which introduces a contribution to the book needed for engineering practice.
Finally, several parts of the presented material are a result of work in the
research field.
There are numerous books about communications technologies providing a basic
knowledge for students and engineers. These books cover more or less the topics
which cannot be substituted in learning communications technologies. Having that
in mind, this book is written in a way that these essential topics are also present, but
not with too many details which can be found in already existing literature. For
example, topics on modulation, line coding and transmission channel are placed in
one chapter, instead of three separate chapters, which is a common practice in most
of literature. Similarly, information theory and source and channel coding are also
merged into one chapter.
Instead, several topics which are not emphasized in most of the general books
about communications technologies find more place and a greater emphasis in this
book, as they are important for the state-of-the-art and possibly future development
of communications. Therefore, one chapter is devoted only to the transmission over
the wireless channel as wireless communications are dominating nowadays; another
chapter is dedicated to wired transmission with accent to modern digital technologies
and optical transmission, and a separate chapter addresses cryptography,
which is inescapable in today’s communication systems.
It is never easy to find the optimal amount of content and to introduce the
needed background of mathematics and physics necessary for understandable and
sufficient explanation of different topics, terms and concepts. This task is even more
difficult when the technology from the past has to be jointly explained with the
modern one, especially considering the fast progress and merging of communications
technologies. It is up to the reader to estimate how far the book succeeded in
the trial to put the basic knowledge together with the modern trends. |
