The paper proposes a customized frequency domain energy detection spectrum sensing scheme. It is needed to fulfill requirements provided by the IEEE 802.22 standard, aimed at extending Internet services to Television White Space frequencies. It provides a detection scheme allowing to achieve strict sensitivity required by the protocol either in sensing time or in detection capabilities. In particular, considered constraints in time and computational burden are tailored to make the method effective in low cost Software Defined Radios, that are envisioned to be typical devices working into IEEE 802.22 framework. Such method should guarantee stability and repetability in its performance. Therefore, the authors propose to combine standard ROC curve analysis to measurement accuracy evaluation, to return the optimal work-point.
