First time I used the text book written by Sir B. P. Lathi as an undergraduate student in 1982. The book was called Communication Systems for our course with the same name. That was an excellent book and gave good mathematical treatment, basically on Analog Communication System. After graduating as MSEE I have been using his two books for teaching communication systems. This Title "Modern Digital and Analog Communication Systems as primary text and "Linear Systems and Signals" as supporting text for course on Communication Systems. Though other books from Haykin, Proakis, Couch, Stern, Zimmer, etc. have been useful to me as well, yet the simplified manner in which B. P. Lathi explains concepts supported by mathematical models is unique and liked by my students as well. It is worth noting that concepts of Information Theory are introduced at undergraduate level only in this text book as a separate chapter. This helps in understanding the connection between Communication Theory and Information Theory. This was available even in his first text book written in 1960s. With the inclusion of MATLAB examples it has become easy to understand and comprehend the performance of various modulation schemes.

However, keeping in view the increased importance of Wireless Communication, the topics related to multicarrier communication (OFDM), error control, channel models, and MIMO system, could have been expanded, perhaps as a separate chapter, like it is done by Prof Gallager in his new book " Introduction to Digital Communication".

About 20 years ago, this book was my introduction to communication systems. Without the fundamentals I learned from this book, I would have never been able to work in the field of communications. I like this book because it is highly readable and covers important topics which communication engineers must understand. This fourth edition provides not only expanded MATLAB examples but covers also more recent material on the subject of communication systems. I'd recommend this book for undergrad/grad students willing to understand the basics of analog and digital communications.

I needed to take a Computer Engineering course at my university that required this textbook, and ordered it on Amazon because they had the best deal. It shipped fast, and the book is of great quality. It feels very dense, like a tome, and you can feel the load of knowledge in it.

There's two major gripes I have with this textbook.

1. There is a major shortage of example problems. Following along with each chapter is difficult, especially as the material gets more difficult or abstract. What few examples it does contain are vague and don't reference the material very well. Examples are critical in truly understanding how solve a problem.

2. There are more homework problems than you would ever like to do, however there are no solutions for these problems. Considering the complexity and difficulty of the problems, even a simple one-liner in the back for each problem would be helpful, like most math textbooks. It's incredibly frustrating to spend hours working on problems only to realize in class you were doing them wrong.

This book is only a success with a very good professor. If your professor doesn't teach very well, you need to find the solutions to the homework problems, to have some sort of reference. Honestly.

I have the 3rd ed. of this book and find it a great book - very carefully written and easy to follow. This made me buy the 4th ed. of the same (used) book because, as has been advertised, the new (4th) ed. contains some new topics like OFDM, 802.11a/b/g/n, DSL, MIMO, LDPC, etc. However, even before I finish reading Chapter 3 of the book, I have discovered some typos of the new book already, some of which were not found in the 3rd edition. Example typos are in Eq. 2.66(p.49), Eq. 3.16(p.99), Eq. 3.17(p.100), Fig. 3.9b(p.101), Fig. 3.10a&b(p.102), Fig. 3.16a&b(p.109), Fig. 3.17a&b(p.111), Fig. 3.18b(p.111), Fig. 3.20b(p.113), Fig. 3.22b&d(p.116), footnote on tp(p.127), Fig. 3.29b(p.130), Fig. 3.41a(p.145), etc. While I am not sure if a list of errata of the book has been provided to the readers, my trust on the book has been lowered quite a bit as compared to its previous (3rd) edition.

I am disappointed at this seller because I paid for 2 hard copy books and I received 2 international editions. If that would have been listed on amazon that would have been fine but you don't advertise one item for sale and ship a different one. Now I have to take the time and review the book to make it is not different from the original edition and if not it might be another moth before I get the right book.

This book is pretty good, it actually makes sense. I've coupled it with Schaum's Outline of Signals and Systems, Second Edition (Schaum's Outline Series) that I had left over from undergrad, for extra help in remembering FFTs. There are good examples, too. No answers in the back of the book though, which is rough, and makes this book lose a star.

I can usually do well in a class that has a lousy professor if I have a good book. This is not one of those books. The book was clearly not written by a native English speaker. It is BORING, and poorly written. There are very few examples. It is riddled with grammatical and numerical errors, and the language does not flow.

It seems like the author wrote this book with the intent of sounding smart, instead of with the intent to teach. You are expected to know and remember many things that many of us once learned, and since forgot. I give it a big thumbs down. I'll give the book two stars for effort. But that's a stretch.

Excellent product, new, reader as shown in the ad!
Super fast delivery, I have nothing to say against the product!
The product was much cheaper than buying in my country!

The answers to this book are a little confusing when you look up homework problems about whether or not to use 2*pi* frequency or Omega (w) in the Fourier equation. Other than that It was an o.k. book seen worse. If you are a teacher thinking about this book I think I would compare last one I think that one was more organized. Not exactly sure though only seen it a few chapters.
Don't take my word for it research it.
