Product Description
Review
'Professor Doyle's book is an enjoyable read. This book could be used as part of graduate studies on software radios and trends in radio design. … It is rare to find the balance of practical depth and high-level vision that comes together in this book.' IEEE Microwave Magazine
'The overall description is very intuitive … It requires no particular knowledge (or mathematical skills) to understand the notions developed in the book. This makes the book very easy to understand, and, thus, accessible to a large public. … As a practical guide on cognitive radio, this book completely fulfills its objective and is very useful for quickly entering into the domain.' Radio Science Bulletin

5.0 out of 5 stars
The Joy of Complex Technology simply explained.,
By
This review is from: Essentials of Cognitive Radio (The Cambridge Wireless Essentials Series) (Hardcover)
This, at first sight, deceptively simple book has an almost addictively pleasurable knack of leading the reader from concepts as simple as an Observe, Decide, Act cycle into the layers of implied complexity related to the mechanisms of Observing, Deciding and Acting through to the implications for Economic Policy on Spectrum Management and Trading that are right on the bleeding edge of multidisciplinary research.
I often found myself shocked by the implications of the assertions in the book as I realised the amount of unlearning that will need to be done by Network Planning organisations in cellular and telephone operators as well as regulators and ministers of government all over the world to cope with the introduction of this technology. The Radio is no longer just an RF device with a limited processor executing a protocol stack but in fact a manifestation of the Semantic Web including an inference engine to deal with cooperative optimisation of many multichannel devices in a given geographic area covered by many heterogeneous communications systems and a given regulatory system. The book does not profess to offer solutions to the many aspects of designing a real mobile network using the devices as there is no description of how Handover will be handled in such a complex environment or how Call or Session Quality can be guaranteed . One simply needs to imagine the extent of the state explosion there will be in tracking neighbour cell information to understand the complexity of this subject. I expect there is at least one, of the many PhDs that this book will spawn, related to guaranteeing Quality of Experience and Quality of Service in the environment with limited control of channel dimensioning. What it does do is describe the totality of knowledge that is needed to successfully design a working system using the technique and so should be read by senior managers to understand the shape of their transformed Engineering and Regulatory Departments and the improvements required in the skillbase. The origins of the book in a department of an outstanding academic institution are obvious and the reader may experience a sense of déjà vu as he or she is led from simple basic concepts just as he or she was in undergraduate lectures into the complexity of Nash Equilibria in the context of game theory and the Ontology required to model the communication environment. If you think you know everything there is to know about a particular piece of technology then you can skip any pages that seem to be old hat, but at risk of missing the gem you don't know about. The real joy of the book comes from discovering that the system is already being prepared for practical use in TV white spaces, and the discussion of the myriad choices for the choice of processing environment for mass market production. Professor Doyle does a remarkable job in explaining a wide range of subjects each of which really deserves to spawn a book of their own on the application of the subject to the concept of cognitive radio. Any required mathematics can be found in the many references at the end of each chapter. I will be surprised if there aren't students fighting to attend her classes and operators queuing up to sponsor her work.

bit soft on the technical side,
By
This review is from: Essentials of Cognitive Radio (The Cambridge Wireless Essentials Series) (Hardcover)
This book has a catchy title, nothing less than an invitation to a view of the new hot topic in radio, all in 200 pages. It's not a bad book but I felt a bit short changed: a lot of blabla but not much on the technical side of things. Same goes for the spectrum book in the same series, unlike the radio propagation volume by Haslett, which DOES have meat. I would recommend to skim this at the library, and to go to IEEE papers and others for the real thing, waiting for some serious books that seem to be coming up.

many unresolved topics,
By W Boudville - Published on Amazon.com
This review is from: Essentials of Cognitive Radio (The Cambridge Wireless Essentials Series) (Hardcover)
For someone possibly not a radio engineer, Doyle writes a non-technical account of what cognitive radio means. Unlike many texts on radios, there is scarcely an equation here. What the book focuses on are the main problems in cooperative behaviour needed when there is a network of CR nodes.
She shows that numerous aspects remain unsolved, or at least without a consensus about a preferred implementation. The general problem is easy enough to understand. Where a spectral range assigned to a primary user might be de facto underutilised at several time ranges. Thus it would be nice if secondary users could sneak in and temporarily use an unoccupied spectral range, but then quickly cease when detecting that the primary user comes back on. All this is where the primary and secondary users transmit and receive in some mutally accessible geographic region; hence that interference can occur if the secondary users are not careful. The prospects of more efficient spectral usage is the main motivator for CR. But my impression from the book is that the plethora of unresolved topics puts CR far off. Maybe an incremental approach could work. Where certain aspects, like smart antennas and MIMO get increasingly incorporated into new radios, and a full CR is deferred. |
