Summary: Good overview but not mathematically rigorous
Review: 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.

Summary: me parece un libro muy completo en cuanto a comunicaciones
Review: Es un libro que permite adentrar a los estudiantes al mundo de las comunicaciones. Con esto el alumno llevará bases solidas para estudios posteriores

Summary: Ho hum
Review: I found this book to have a decent amount of discussion on channel and source coding, baseband and CDMA modulation and demodulation. But NO echo cancellation or DMT and a few paragraphs on channel equalization!?! This book is very readable if you are looking for some fundamentals and common topics, but it's also missing some important stuff. OTOH, I'd really recommend Lee&Messerschmitt's Digital Communication if you need a great reference book.

Summary: Comprehensive, yet easy to understand digital comms text
Review: I have not read the first edition, but I have long depended on Sklar's tutorial articles in various publications to improve my understanding of digital comms concepts, so it was with some anticipation that I opened this book. It certainly did not disappoint; the author's characteristic style, which imparts an intuitive understanding rather than simply instruct, is present throughout. In certain sections, the theory is not just presented alone but supplemented with nuggets of practical knowledge. Proakis is undoubtedly still the benchmark for such texts, but this book will be a valuable addition to the bookshelf for both students and engineers alike. Remember to have a look at the checklist in the preface to straighten out your concepts.

Summary: The greatest digital communications books of our age!
Review: I initially was introduced to the book when I took the course in undergraduate electrical engineering curriculum. A graduate curriculum and a year of engineering experience later, I still believe this book is one of the best engineering books, one of the most useful communications books, the best reference book to own and utilize as an engineer. Sklar has a clear vision of the abstract mathematics and complex concepts of the communication world and he transfers that vision into words, pictures, and crystal clear descriptions. Highly recommended even for general reading.

Summary: A great book to learn comm. theory.
Review: I was introduced to the 1st edition of this book as an undergrad at UCLA where Sklar taught. Since then as I have worked in the wireless and telecom fields, it has remained one of my main references. I've added other comm. books such as Proakis', but Sklar remains my favorite. It is well arrange, making it easy to reference any material you may be interested in. It touches on every area of comm. theory from modulation to coding. If you are looking for a general communication theory reference book, then this should be the one. But if you are only interested in learning in detail about one particular area of commmuncation theory such as CDMA or Trellis Coding, then you should seek a book specializing in that area only. No book can cover everything in the depth.

Summary: Excellent resource in the field of Digital Communications
Review: Professor Sklar's book in Digital Communications is most informative, well written and covers all the topics related to digital communications that my colleagues and I use daily at work, as well as in our research. The book provides not only the fundamentals in digital communications, but serves also as a major reference book on advanced topics in this field. I cannot do without it.

Summary: About average as far as textbooks go
Review: 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.
