Spectrum sensing operation based on a real signal of FM radio: Feasibility study using a random sampling mode
Abstract
In this paper, we are interested to the implementation of the spectrum sensing (SS) operation based on a real signal of the FM radio and using a random sampling mode. This application consists on the realization of the spectrum sensing operation based on the energy detector (ED) method combined with random sampling. The analyzed real signal is an FM radio signal captured under GNU-Radio. This application is performed in cognitive radio (CR) systems in order to analyze the occupancy of the radio frequency spectrum. The performance of this approach is evaluated in terms of its receiver operating characteristic curves (ROC curves) and in terms of the false alarm probability. © 2016 IEEE.
