Average Reviews:
(More customer reviews)This book is for the serious student/engineer/scientist that has a solid foundation in math. For such a person this book is a tremendous tool. It explains in the most rigorous way all concepts in the basis of digital comm. No ambiguities are left. Everything is rigorously introduced. I felt like many concepts are more clear now and if you assimilate the material, you'll gain more confidence in dealing with the concepts of digital comm. The author is not afraid of proving important results no matter how long the proof is.
As a unique characteristic (I've read the first 400 pages so far) I could not find but just 1 typo! If you compare this to books like proakis, gallager, goldsmith, Tse, these books have pages and pages of typos. You're almost afraid to start reading them...
With Lapidoth you're in solid ground. Overall a great achievement. I wish and hope that prof. Lapidoth will write a couple of more books on wireless communications, a hot topic where still I cannot find an exceptional textbook (there are several ones that are OK but still with so many errors...).

This intuitive yet rigourous introduction derives the core results of digital communication from first principles. Theory, rather than industry standards, motivates the engineering approaches, and key results are stated with all the required assumptions. The book emphasizes the geometric view, opening with the inner product, the matched filter for its computation, Parseval's theorem, the sampling theorem as an orthonormal expansion, the isometry between passband signals and their baseband representation, and the spectral-efficiency optimality of quadrature amplitude modulation (QAM). Subsequent chapters address noise, hypothesis testing, Gaussian stochastic processes, and the sufficiency of the matched filter outputs. Uniquely, there is a treatment of white noise without generalized functions, and of the power spectral density without artificial random jitters and random phases in the analysis of QAM. This systematic and insightful book, with over 300 exercises, is ideal for graduate courses in digital communication, and for anyone asking 'why' and not just 'how'.
