Abstract

This paper presents a novel energy based multiresolution spectrum sensing technique. By applying an efficient flexible FFT, the proposed method can focus on a small part of the interested bands with finer resolutions at low computational cost. The hardware implementation of the algorithm has been considered. An experiment on a reconfigurable platform shows that the algorithm is not only computationally efficient but can also easy to be reconfigured easily and fast.
