For second and third year introductory communication systems courses for undergraduates, or an introductory graduate course. This revision of Couch's authoritative text provides the latest treatment of digital communication systems. The author balances coverage of both digital and analog communication systems, with an emphasis on design. Students will gain a working knowledge of both classical mathematical and personal computer methods to analyze, design, and simulate modern communication systems. MATLAB is integrated throughout.

These comments refer to the 7th edition from 2007. This is an excellent but also difficult textbook. According to the preface, the book is intended for junior and senior level undergraduates, but it seems more of a graduate level book to me. Dr. Couch does not ask the reader to take anything on faith; he provides a proof of every theorem, or otherwise gives a reference which contains a proof. As a result, some chapters contain over 200 equations. However, most of the math involved is no more difficult than second-semester calculus, and circuit analysis can be helpful for some elementary circuits like RC networks. A signal processing course will definitely make things easier for you. There are only eight chapters in the book, with an average length of 80 pages. Most concepts are clearly explained, and there are around a dozen examples in each chapter, most of them running more than a full page.“Analog” may seem old-fashioned and unnecessary in a digital world, but every communicated signal will be analog at some point, so it’s important to know both sides of communications. This text is evenly divided between analog and digital communication. For example, the chapter on noise corruption is divided between Bit Error Rate of digital systems and Signal to Noise ratios of analog systems. Most circuits, both analog and digital, are described by block diagrams, so you don’t need to know much electronics or circuit analysis. The last chapter is a technical description of wired, wireless, and satellite systems as of 2007.
What offsets the difficult and sometimes tedious nature of this text is the unusual amount of support Dr. Couch provides to students. Each chapter ends with four to six “Study-Aid Examples,” which work through a problem related to the chapter. There is also a very helpful appendix on probability and random variables, which provides a good introduction to the chapter on random processes. About a third of end-of-chapter problems have solutions in the back of the book, and all of those have fully worked-out solutions downloadable from the author’s website. Also on that website are a large number of Matlab files which either accompany solutions or illustrate some point in the text. So in spite of being a difficult textbook, it is one of the better choices for self-study, since other texts often provide NO solutions to end-of-chapter problems. It’s been a lot of effort to get through this book, but I’m glad I did.

Digital Analog Communication Systems Leon W Couch Books Reviews
I had to use this book for one of my undergrad classes. It was not at all helpful. The material is presented in a very boring fashion with not enough explanation to do any hw problems on the material. The least it could do is do some examples that actually show you how they got the solution. The instructor did not help much either which made me hate communications.
Great book. Even though it was used, the description fit the actual state of the book As new. The only thing is that the last set of pages were detached from the rest of the book, but still beats the expensive prices of buying it completely new without sacrificing much quality.
Thank you!
Nice slim book and helpful with this difficult class I am taking.
I was hoping to find it sort of "full of well explained examples" resource, yet at this stage almost one year after passing the subject I believe this purchase was "unnecessary". For some reasons, the author keeps trying to "complexify" the topics which essentially are complex enough by themselves! while looking up if you're lucky you will see a short example of the topic that you're looking for and this happens like every 10 pages. Failure in digging into the topics and failure in explaining the issues with a simple language are the most significant problems that we experienced during the semester when using this book. I believe this subject needs a book with lots of examples and short but effective and right to the point explanations which sadly this book did not have.
Twas a bit risky cause it looks like the book is going to be in Chinese. But I can confirm that this is not the case. The rest is in English. The prologue of the book is in Chinese though. However if you need it there is a copy of the entire book via pdf online (I used to check that the page numbers and content matched what I bought).
This book is a graduate-level introduction to the subject, meaning it makes some assumptions about the reader. For example, it assumes you will not cringe when you see mathematical symbols. That you have been through an undergraduate treatment to signals and systems, Fourier analysis, and an introduction to random processes. While a lot of this is covered as a refresher in Chapter 2 and Chapter 6, it is meant more as a reminder than a primer. It assumes that as you make your way through the book, you won't understand everything at the first attempt but certain sections and/or chapters will require multiple readings. For instance, a section in Chapter 3 may not become clear until you reach the end of Chapter 4. It assumes you will be fine with this, given that this is a complex, dense subject, and that the insights contained here have been developed and perfected by experts in the area for several decades.
The rest of the book does a great job of balancing the analog and digital communication worlds and really explains how they work together. There are other books that cover analog communication theory more deeply - in particular the circuits used in analog comm systems and the issues of nonlinearities in the analog world. There are other books that cover digital communication theory more deeply - in particular, coding techniques and channel equalization. However, you will be hard-pressed to find a book that can do justice to both worlds, and their non-obvious intersection. It is ambitious in its scope and wonderful in its execution.
The writing is first-rate. The author makes sure to repeat aspects of the theory deemed important, often times at the end of a section but also at other times in the text. As a reader, I am thankful for that. The math is rigorous, but the text emphasizes intuition. It is as if one is having a conversation with the author. This is a rare balance in technical books. There are also a large number of exercises, with plenty of MATLAB experiments thrown in. There are solutions to selected exercises at the back. The references (all listed at the back) are also wonderful, and it makes you want to explore the content in more detail.
A note about the price The book is prohibitively expensive. I was tempted to take off a star for this, but I didn't want the price to reflect badly on the author, since it is really a problem with the modern publishing industry. Regardless, get this book, take your time to diligently work through the material, and watch your understanding grow.
