Research of Cognitive Radio Technology Application Cases in the Tasks of Providing Information Needs

The object of consideration is systems of cognitive radio, area and cases of their application in the tasks of technical support of special information needs, in particular, for deep or operational monitoring of the radio broadcasting channels content. The subject of research is the development of software and hardware solutions for special tasks of cognitive radio based on SDR technology, USRP architecture and LabVIEW software environment. The purpose of the research is to formulate and justify the tasks of information service, to justify the possibility and evaluate the effectiveness of SDR technology, USRP architecture and LabVIEW software environment using for specialized hardware and software devices prototyping. The decisions are based on the results of similar studies published in periodicals and on the Internet, but mainly on the results of experimental research by the authors, as well as testing of these results and technical solutions in the educational process. The article is devoted to the search, substantiation of relevance and the formulation of a number of information service tasks using cognitive radio technology, the problems analysis of implementing the corresponding devices based on the prototyping paradigm, the evaluation of these devices using performance to solve a number of information service problems, and the experimental verification of the functionality and quality of the developed prototypes.
