Comparative study of spectrum sensing techniques base on techniques non-cooperative in cognitive radio networks
Prince Semba Yawada, An Jian Wei · 2016
The growing demand of the wireless communications introduced the challenge of the efficient use of the spectrum. Cognitive radio is an emerging technology in the field of wireless access, in order to considerably improve the use of the radio spectrum by allowing access of opportunistic manner. The detection of the spectrum is the basic functionality in a cognitive radio that is why in this paper a particular emphasis is placed on the comparison of the different methods of detection of the spectrum in the case of detection non-cooperative. We note that the different techniques do not present the same performance. In this paper the CFD method presents a good performance by report to the MFD and ED. The result of the simulation was obtained through the Software Matlab.
