Title: Not a bad book but needs significant improvement
Review: I am a lecturer and used this book for my class.I like the material presented in this book. It contains many examples and discussion on real applications. However the organization of this book is not good. It is just like putting several people's work together without appropriate coordination of the material.As a second edition of the book, it contains too much errors. You can find many errors in almost each chapter. I have to check carefully before I use their examples, equations and solutions. Otherwise I will get embarassed by letting the students pointing it out in my lecture. It is absolutely a shame.If you are an engineer who are already familiar with data communications and can tell those errors, this book is a good choice. But if you are a student, I sugget you stay away from it unless it is the textbook chosen by your lecturer.
