Two years ago I received my copy of Fette's First Edition, and wrote a review indicating that it would be a useful reference for participants in the maturing Software Defined Radio and emerging Cognitive Radio technology. As I pick up my copy of the original book, a massive number of bookmarks and plethora of underlining attest to the accuracy of that prediction. As a regular participant in the Software Defined Radio Forum's work in this area, I habitually reach for this book to understand the context of our ongoing technical work.
The Second Edition adds eight new chapters to the previous sixteen; it constrains the size of the book to an additional 206 pages by using a smaller typeface (which actually improves readability). Page composition is also improved with an appealing layout and very helpful headers: the Chapter name on the left, and section name on the facing pages.
This book is not a bedtime read; rather it is encyclopedic in its approach. Individual articles are derived from the work context of authors, who are authoritative in their own areas. Reading technical journals is made difficult (as observed by Thomas Kuhn) by the convention that the reader is fully knowledgeable about the topic under discussion. This volume takes material that would be (or already has been) published, and provides a context for it. Fette has retained his "book-end" approach, with the first and last (moved from 16th to 24th) chapters in which he explains the relevance of the material in each chapter. Then each article has introductory and conclusionary material often not included in published papers.
The new chapters address topics such as Cognitive antennas, Spectrum Sensing, Rendezvous, and Networking. They significantly increase the book's utility. In looking over the discussion of Policy-Driven CR Architecture, for example, I found myself drawn to the website of the Maude language; an excursion that provides an example of how the articles can be used as an introduction to a topic, with updates and expansions obtained by using references and browsing websites.
The classical means of making a scientific discipline clear and consistent (again according to Kuhn) is through textbooks. But the contemporary velocity of technological advancement renders that approach impractical, so this book provides timely information by not waiting for issue resolution.
There is something here for virtually everyone working in the area, from high-level overviews to mind-consuming mathematical depth. Many of our legacy information institutions are rocking from advances in (or misuse of?) Cognitive functionality (e.g. banks); this book provides valuable insight into the specific technologies that will arm us to cope with the impending information tsunami.
