Читать книгу Dynamic Spectrum Access Decisions - George F. Elmasry - Страница 21

DSA solutions can differ drastically from one system to another. However, there are common foundations that can be used in any DSA design approach. The goal is always the same: optimize the use of a given pool of spectrum resources dynamically and react to changes in environments. With this book laying some theoretical foundations of DSA design, addressing the most generic model of DSA, and then showing with case studies how this generic model can be applied to different cases, the reader should be able to obtain knowledge on how to approach DSA and how to create design concepts for any system under consideration. The separation of the physical layer aspects of DSA from the cognitive engine aspects in this book should help the reader address the design aspects of the physical layer separate from the design aspects of cognitive engines such that DSA can be applied to noncognitive systems and cognitive systems and the design can address any system requirements and boundaries.

As the reader goes through the rest of this book, the many facets of DSA will become clearer and the reader will see how a large system of heterogeneous networks may require using heuristic approaches, overlaying of decisions‐making processes, and considering many aspects and tradeoffs to design an effective system.
