Treffer: Channel Sensing in Cognitive Radio by Using MATLAB.

The development in wireless communication, along with various applications, has put so many limitations on the use of radio spectrum. When we look at spectrum utilization, most of the times, the radio spectrum is not used properly. Some of the frequency bands in the spectrum are unoccupied, some frequency bands are less occupied, and a few bands are heavily occupied. Cognitive radio is the novel concept which can successfully deal with the growing demand and scarcity of wireless spectrum by effectively utilizing the unoccupied frequency bands. Cognitive radio is an intelligent wireless architecture which searches the spectrum holes and allows unlicensed users to access licensed spectrum bands. Spectrum sensing is used to detect the spectrum holes, providing high spectrum resolution capability. We have generated an experimental model of cognitive radio system using MATLAB. In this paper, we delve into the idea of simulating cognitive radio system for effective utilization of vacant frequency bands. The performance of cognitive radio has been tested using MATLAB R2012a.
