—Cognitive Radio (CR) systems with spectrum awareness feature is a promising approach to use spectrum effectively. However, accurate modeling of spectrum utilization is crucial for the development and performance evaluation of such systems. Hence, in this paper, a wideband multidimensional spectrum occupancy measurement campaign is conducted to study the(More)
—Spectrum awareness is an essential part of Cognitive Radio (CR) systems that enables CR systems to intelligently utilise the spectrum. Accurate modeling of spectrum utilization is crucial for the development and performance evaluation of such systems. In this paper, a wideband spectrum occupancy measurement campaign is conducted to study the utilization of(More)
— Cognitive radio networks that employ the dispersed spectrum utilization as spectrum access method are called dispersed spectrum cognitive radio networks. In this paper, we derive the effective transport capacity of adhoc dispersed spectrum cognitive radio networks in which the nodes are distributed in three dimensional (3D) configurations. The analysis is(More)
