Über dieses Buch

The aim of this book is to provide some useful methods to improve the spectrum sensing performance in a systematic way, and point out an effective method for the application of cognitive radio technology in wireless communications. The book gives a a state-of-the-art survey and proposes some new cooperative spectrum sensing (CSS) methods attempting to achieve better performance. For each CSS, the main idea and corresponding algorithm design are elaborated in detail. This book covers the fundamental concepts and the core technologies of CSS, especially its latest developments. Each chapter is presented in a self-sufficient and independent way so that the reader can select the chapters interesting to them. The methodologies are described in detail so that the readers can repeat the corresponding experiments easily. It will be a useful book for researchers helping them to understand the classifications of CSS, inspiring new ideas about the novel CSS technology for CR, and learning new ideas from the current status of CSS. For engineers, it will be a good guidebook to develop practical applications for CSS.

Chapter 6. CSS Based on Soft Combination

Abstract
The CSS based on hard combination is analyzed in the previous chapter. In this chapter, the CSS based on soft combination is illustrated, which can be used to improve the CSS performance by introducing weighting factors. In the following, the system model and some optimal algorithms are shown from theory to simulation results respectively.

Chapter 7. The SS Application in ICIC

Abstract
In this chapter, an inter-cell interference coordination method by spectrum sensing technology is studied, where, the terminal with cognitive function can automatically detect the available spectrum when requesting for service, and select the idle spectrum or the occupied spectrum with the weakest signal strength to realize the actual weakest interference communication, make the reduced inter-cell interference and improved cell edge user’s performance.
