This book was not intended as a communication theory text, but it does a great job of providing the basic results in an organized fashion. It serves as a good reference for me for CDMA related issues, or channel models and fading/diversity analysis.
Definitely recommend the book if you can find one at a decent price. Five stars is granted for the reference use of this book, this should not be a first timers' textbook.
Artech House books are usually packed with errors, since there is no serious review process. But refreshingly this book does not come with a big pack of errata despite the large content.
