This is an undergraduate-level textbook that lucidly provides the basic princi-
ples in the analysis and design of digital communication systems. Since digital
communications is an advanced topic, the treatment here is more descriptive
and explanatory rather than merely rigorous. However, it is not devoid of math-
ematical analyses, as all relevant results are presented. Although the mathemat-
ical level of the book is intentionally constrained, the intuitive level of it is not.
The premise is that complex concepts are best conveyed in the simplest possible
context. The goal, at every step of the way, is to provide big picture through
analysis, description, example, and application. In taking a systems approach
to digital communications, the text hardly considers actual physical realiza-
tions of the devices (i.e., the systems are presented in block diagram form).
There is intentionally much more in this book than can be taught in one semes-
ter (of 36 lecture hours). The book consists of 12 chapters focused on digital
communications. Chapters 1 & 2 provide an overview of the fundamentals
of digital communications. Since digital communications at the physical layer
involves the transmission of continuous-time signals where the channel noise
is also in the form of continuous time, Chapters 3 & 4 cover deterministic and
random signals in detail, and should serve as review materials. Chapters 5 to 12,
inclusive, discuss the critical elements and major topics in the broad field of
digital communications. In addition, there is an appendix with a summary
of analog communications.
