Communications technologies increasingly pervade our everyday
lives, yet the underlying principles are a mystery to most. Even
among engineers and technicians, understanding of this complex
subject remains limited. However, there is undeniably a growing
need for all technology disciplines to gain intimate awareness of
how their fields are affected by a more densely networked world.

The computer science field in particular is profoundly affected
by the growing dominance of communications, and computer scientists
must increasingly engage with electrical engineering concepts. Yet
communications technology is often perceived as a challenging
subject with a steep learning curve.

To address this need, the authors have transformed
classroom-tested materials into this accessible textbook to give
readers an intimate understanding of fundamental communications
concepts. Readers are introduced to the key essentials, and each
selected topic is discussed in detail to promote mastery. Engineers
and computer scientists will gain an understanding of concepts that
can be readily applied to their respective fields, as well as
provide the foundation for more advanced study of
communications.

* Provides a thorough grounding in the basics by focusing on
select key concepts

* Clarifies comprehension of the subject via detailed explanation
and illustration

* Helps develop an intuitive sense of both digital and analog
principles

* Introduces key broadcasting, wireless and wired systems

* Helps bridge the knowledge gap between software and electrical
engineering

* Requires only basic calculus and trigonometry skills

* Classroom tested in undergraduate CS and EE programs

Communications Engineering by Lee, Chiu, and Lin will
give advanced undergraduates in computer science and beginning
students of electrical engineering a rounded understanding of
communications technologies. The book also serves as a key
introduction to specialists in industry, or anyone who desires a
working understanding of communications technologies.
