LOPEZ, Danilo A; TRUJILLO, Edwin R  e  GUALDRON, Oscar E. Basic Elements that Compose Cognitive Radio and Mapping Spectral Bands. Inf. tecnol. [online]. 2015, vol.26, n.1, pp.23-40. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642015000100004.

Fundamental elements of the cognitive radio and assignment of spectral bands are described and analyzed. Among the main problems in the insertion of new applications and wireless technologies is the lack of radio spectrum for allocation due to the inefficient distribution of available radio spectrum, which is statically allocated at present. The cognitive radio paradigm was born as a method for proposing a solution to the problem, dynamically managing the resource. One of the stages that make up this technology is the decision of the spectrum that selects and allocates frequency bands based on quality of service requirements of the cognitive users. This article presents a proposal for the development of a research project that optimizes the selection of channel allocation by reducing the time to improve their performance.
