Spectrum Efficiency Maximization in Cognitive Radio Systems

The Optimal Radio Resource Allocation Algorithms Design in Multiband OFDM Ultra Wideband Cognitive Radio Systems

Beschreibung

In the field of cognitive radio, Spectrum Efficiency Maximization in Cognitive Radio Systems makes excellent dynamic radio resource allocation algorithm design for the professional. Based on the low-power multiband Orthogonal Frequency Division Multiplexing (OFDM) Ultra Wideband (UWB) system, the book gives a comprehensive and in-depth analysis in the technologies of UWB and Cognitive Radio, formulates the spectrum efficiency maximization problem into a multidimensional multi-knapsack problem, and provides a solution to the optimization problem by creating three novel low-complexity algorithms for spectrum sensing and spectrum management. Simulations and mathematical analysis show that the new algorithms significantly increase the spectrum efficiency of the low-power UWB-based cognitive radio system with very low cost compared with the conventional radio resource allocation algorithms, such as water-filling and Hughes-Hartogs algorithm. The book provides a solid foundation for the future study in large-extent and high-density multiuser cognitive radio networks, which can fully explore the benefits of cognitive radio technology.
