ABSTRACT
The increasing demand for higher data rates in communication systems requires an efficient utilization of the limited frequency spectrum resource. Therefore, cognitive radio aspects are of utmost interest. The authors propose a reconfigurable cognitive radio platform which combines the advantages of the flexibility of a digital signal processor with the efficient parallelization capabilities of a field-programmable gate array. Since the ever increasing computational complexity complicates the dimensioning of such platforms, scalability and modularity was a crucial design constraint for the presented concept.

Dynamic spectrum allocation with variable bandwidth for cognitive radio systems
ISCIT'09: Proceedings of the 9th international conference on Communications and information technologiesCognitive radio networks can be designed to manage the radio spectrum more efficiently by utilizing the spectrum holes in primary user's licensed frequency bands. The currently available unlicensed spectrum is reaching its limit and various demands for ...
Optimized Spectrum Sensing Algorithm for Cognitive Radio
The electromagnetic spectrum is a meager resource of nature. The current standing spectrum allocation policy is unable to put up the demands of wireless communication. This leads to self-motivated spectrum allocation policy. Cognitive radio (CR) ...
Spectrum sharing in cognitive radio networks: an auction-based approach
Special issue on game theoryCognitive radio is emerging as a promising technique to improve the utilization of the radio frequency spectrum. In this paper, we consider the problem of spectrum sharing among primary (or "licensed") users (PUs) and secondary (or "unlicensed") users (...
