telecommunications

Digital Communications by Sklar is an excellent introduction to the field for the student or the practicing engineer. There is a logical flow from beginning to end, and the book is written in an easy to read style, which allows the reader to grasp the engineering tradeoffs involved in digital communications.

The book is not mathematically rigorous; although formulas are presented, they are not derived. However, I feel that to correct this shortfall may make the book too long, and harder to read. I think it is better to get a general overview of the topic from this book, and to look to other sources where mathematical rigor is desired.

Some additional background is helpful, but not necessary to understand the mathematical details that are glossed over. These include a course in Detection and Estimation to understand concepts such as signal spaces, noise, decision regions and probability of error, and an introductory DSP course to understand the issues surrounding aliasing, quantizing, equalization, and source coding. Familiarity with Fourier Transforms and prior background with Probability and Random Processes is essential to understanding the math that is presented in the book.

Overall, I highly recommend this book for someone who wants to appreciate the engineeering constraints that need to be met in the design of digital communication systems.

This is one of the best books on the market for communications. As a university professor I am always looking for that special book that can take the student from the formative learning stage into maturity in the field of communication and signal processing. This book is an excellent text for such a journey. It provides a good mix of theory and practice with many worked examples. Unlike many texts in communications theory that provide their audiences with a lot of theory and abstractions that leave them confused, this book is so well written and the theory so well handled and presented, that its concepts are easily grasped. Then, to supplement this, the book has numerous worked examples showing practical applications. As an educator in the field of communications I have adapted this book for my course because its stated attributes above make my work in educating students that much easier. I recommend this book without reservation to anyone who needs a good reference in the field of communications.

Sklar covers a lot of material fairly well. At times his explanations are not clear. At his weakest moments he leaned heavily on mathematics without supplying much discussion and left me more or less bewildered. I noticed this problem with many texts during the spent 6 years I spent in graduate school studying physics. "Digital Comm" is a fair book but not a gem.
