Abstract
Despite its practical performance limitations, energy detection has gained popularity during the last years as a
spectrum sensing technique for dynamic spectrum access in cognitive
radio networks. The main advantages of energy detectionbased spectrum sensing are its simplicity, low computational and
implementation costs as well as its ability to work irrespective of the actual signal to be detected. Since no prior knowledge is
required, energy detection can be employed when the secondary receiver cannot gather sufficient information about the primary
user signal. Due to the generality of its operating principle, the energy detector performance would not be expected to
depend on the type of primary signal being detected. In this context, this paper evaluates the performance of energy detectionbased spectrum sensing for several real-world primary signals of
various radio technologies. The obtained results indicate that the
detection performances may vary notably with the considered primary signal but converge under certain conditions. The practical consequences of the different observed performances for several primary radio technologies are illustrated and discussed.
