Summary: A nice book with some errors
Comment: Dr. Haykin's book on Communication Systems is one of the standard textbook in the world. It is the first book from which many EE students start to learn the theory of communications. I have used several books written by Dr. Proakis and Dr. Haykin in my class for many years. Haykin's book features complete (and concise) coverage of fundamental topics in communications, and is mathmatically clear.
However, the high standard required for an excellent writer is not completely achieved in this book.
First, in Example 1.3 (middle of Page 39), the derivation process of the conditional expectation is misleading: the condition $t_dSecondly, in Eq. (1.98) (Page 63), the dummy variable t inside an integral appears in w'(t), which is obviously wrong.
Thirdly, in Eq. (3.20) (Page 191), the absolute value symbol is missing in two terms related to the magnitude |H(f)|. Also, in Figure 3.6 (b) (Page 190), the phase arg[H(f)] is not illustrated correctly.
There are other errors throughout this book (even in the 4th Edition!).
Also, many problems in Haykin's book are quite lengthy and not well-suited for midterm and final exams from an instructor's perspective.
I wonder where to find an error-free comprehensive textbook in the field of telecommunications like Knuth's (hard to read, though) in computer science.
Compared with other textbooks in communications, this book still ranks among the best in terms of its clarity, illustratoins, and comprehensive coverage - if and only if the errors aforementioned can be corrected.

Summary: What it is about, is left for you to figure out.
Comment: To the best of my knowledge, this is the first undergraduate book on communication systems to include introductory treatments of time-frequency analysis and cryptography. Three years ago when I took my first communications course, I have used this book as a reference. "Modern digital and analog communication systems", second edition by P. B. Lathi, was the adapted textbook by my professor. I had four books to study the subject from; Lathi, Haykin, Zimer and Tranter, and Leon W. Couch II. Because Haykin was the most popular, I though that it was the one that I should concentrate on. Upon completion of reading each chapter, I had more questions than answers, so I had each time to turn to Lathi and Zimer, which I found much more fluid and accessible. Couch's "Digital and analog communication systems" is simply a piece of garbage. After reading Lathi's "Modern digital and analog communication systems", for analog communications course, B. Sklar for digital communications course, I gained an adequate maturity on the subject such that enabled me to read Proakis's "Digital communications", third edition, which I found to be the most serious and involved book on the subject. I still think that Haykin's "Communication systems", is very much similar to Kant's "Critique of pure reason", since you have to read the same thing over and over again until you reach the point where you start wondering "have I understood it, or is it the repetition that made me memorize the subject?!". Imagine Bertrand Russell or Kurt Godel trying to explain multiplication and division to the first grade students, the situation is analogues, Haykin, world leading communication researcher trying to explain introductory analog communication principles and digital pass band transmission to senior students, he must admit that it isn't easy to imitate R. Hamming's insightful writing style. Chapter 2 starts very well, until section 5, where the author is pointlessly trying to mention uncertainty principle, and yet, he does not. Maybe in next edition, he will include a section on Wigner distributions and somehow manage to mention tensor product. In 2.11 concept of pre-envelope is discussed in very dry manner, maybe in the next edition it will be mentioned that the real and imaginary parts of an analytic function are harmonics and in the footnote complete theory of harmonic analysis will be summarized in 5 lines. Chapter 4, Random Processes doesn't even mention optimal filtering, the subject that arises naturally in the context of signal recovery. In next edition it is expected that chaotic dynamics of the sea clutter will be compressed in a single section. Don't waste your time on chapter 5, read Lathi's (1998) chapters 12 and 13 on the same subject. Section 6.13 unfortunately doesn't include filter banks, pyramid algorithms, quadrature mirror filters and thorough five-line discussion of multi-resolution analysis. Section 7.9 does not include generalization of LMS algorithm to error back propagation, and blind deconvolution is not even mentioned. Section 8.4 on geometric interpretation of signals says nothing about Banach spaces, nor Frames. It's true that section 8.6 includes very nice discussion of coherent detection of signals in noise, but for partially coherent, deferentially coherent and double deferentially coherent communications with waveforms the reader is advised to refer to "Digital communication techniques, signal design and detection", by M. K. Simon and S. M. Hinedi, 1995. Chapter 9 on spread spectrum modulation says no more than 16 lines about synchronization, the subject that is given four pages in B. Sklar (1988). Delay locked loops does not even ring a bell. Don't you agree that synchronization is one of the main issues in the spread spectrum systems? Add to that, that examples of pseudo-random codes given in this book do not exceed periods of 256 bit length, that is less than one microsecond of randomness, while practically attainable periods are of one century duration. Anyway, for a better one chapter treatment of spread spectrum systems refer to Proakis. Section 10.13 "Compression of information" has very nice comprehensive 9 lines on vector quantization. Maybe in next edition "Information-theoretic models" and "Radial basis function networks", will be included as a section in this chapter. Don't waste your time on chapter11 "Error control codes", read B. Sklar's (1988) chapters 5 and 6. Chapter 12, what it is about is left for you to figure out. Let me conclude by saying that "Communication systems" is an undergraduate text written with graduate language. I found Haykin's "Neural networks, a comprehensive foundation", in order of magnitude superior to any other book on the subject. Meanwhile I am using his "Adaptive filter theory" to gain enough knowledge about the subject for my current project on system identification with LMS implemented with FPGA. If you are a beginner in communication systems subject, use your time efficiently by reading Lathi and Zimer on introductory subjects. If you like to go on further, than get B. Sklar, and then Proakis. Don't get deceived by brain damaged readers who claim that it is the best book as an introduction, maybe they say so, because they have failed in the course over and over again till they decided to memorize all formulas and definitions which they found organized in Haykin's. Also note that tons of universities started to adapt Lathi's instead of Haykin's.

Summary: A BOOK FOR PROFESSORS NOT STUDENTS
Comment: IF YOU WANT TO UNDERSTAND THIS BOOK COMPLETELY YOU MUST READ IT MAY BE HUNDREDS TIMES,IF YOU HAVE TIME!MATHEMATICAL AND LOGICAL EXPLANATIONS ARE ACTUALLY NOT ENOUHG.SOMETHINGS THAT MAY BE EXPLAINED IN A FEW MATHEMATICAL EQUATIONS WERE EXPLAINED IN A LOT OF TEXT.WHY?I REALLY DID NOT UNDERSTAND THAT.
